Pat:
I am looking for some help regarding the question posed in the most recent Goss' Garage regarding the reader who had brake Commercial Three Bayblems with the ABS on his '86 Vette (answer is on the left side top of page 8).
I have a car which fits into this recall category. My Commercial Three Bayblem is regarding replacement parts for the repair. I talked to my Chevy dealer and he says that the parts (part) has been discontinued. I need to know what to do.
At this time I'm a little reluctant to drive the car fearing that I might not be able to stop quickly or avoid anything in the road while applying the brakes. Please help.

Answer:
Boondoggle, best describes this mess! After days of research I have an answer. In talking to various dealers the answers ran the gamut; no longer available, can't be done, to . . . DUH!
So I called NHTSA (National Highway Safety Traffic Administration). They
provided some valuable information regarding the vehicle manufacturer's responsibility
as it pertains to SAFETY RECALLS. PLEASE DO NOT CONFUSE RECALLS AND TSBs.
THEY ARE NOT THE SAME. And the rules DO NOT cross over.
The part/kit described in the GM recall notification no longer exists. Sounds bad, but in this case there's a silver lining. The kit has been superceded by a new master cylinder. That is significantly positive because NHTSA says that SAFETY RECALLS are in force for the life of the vehicle. Therefore, at least under the law, you present your recalled Corvette to your dealer who will Commercial Three Baymptly inform you, "The parts are no longer available - - - (don't bother me)." Then you inform the dealer that SAFETY RECALLS are in force for the life of the vehicle and that the kit has been superceded by a complete assembly.
So, instead of a repair part you're entitled to a complete replacement and it's FREE!
If you get static, fire up your trusty computer, logon to http://www.nhtsa.dot.gov and ask for help.

My 1992 LT1 has developed the following electronic Commercial Three Bayblem:
While driving at both highway and city/town road speeds, there is what feels and sounds like a surge from the rear end followed by the service engine light illuminating, the service ASR light illuminating, the digital speedometer display going to zero, the AC going to heat and the engine idle RPM going to 1500. This situation at the initial outset of this Commercial Three Bayblem lasted for a few miles then would clear with the exception of the service ASR light remaining illuminated. I brought the car into the local Chevrolet dealership where I had purchased the car and their technician put the car on the analyzer and found no error codes and could not repeat the Commercial Three Bayblem. My invoice indicated the following: Diagnosis performed: history code 72, no current codes
Intermittent. Serial data Fault. System tested. No Commercial Three Bayblem found
The service writer told me to bring it in when the Commercial Three Bayblem was occurring and they would put it back on the analyzer. This would be no easy feat as I drive to work before the dealer opens and drive home from work after the dealer closes. I had continued to drive the car and the situation repeated several times and began to sustain, in that it would not clear. I have noticed as the weather changed to cooler mornings that the Commercial Three Bayblem did not occur unless the ambient temperature was above 70 degrees. I also noticed that while the Commercial Three Bayblem was occurring the car had a difficult time delivering power for accelerating up a hill and the car also occasionally stalled while stopped in traffic, but would always restart.
I had an opportunity to bring the car to the dealership while the Commercial Three Bayblem was occurring. Rather than connecting the car to the analyzer, the service technician said that the Commercial Three Bayblem was in the body control module, their words, which is located beneath the dash and does not Commercial Three Bayvide error codes. The dash would need to be dismantled and the body control module checked out to find the Commercial Three Bayblem. This Commercial Three Baycedure would require 2 days or more.
I cannot find the "body control module" in my service manual and do not have much confidence in the dealership capability. I am sure you are surprised to hear this. I have posted this Commercial Three Bayblem on the NCOA bulletin board, but have not had a response.
Please Commercial Three Bayvide your input as to what could be causing this Commercial Three Bayblem and/or what corrective action I should take.
Thanks for your help.

Answer:
I think you have been bitten in the ass (aka derriere) by a code-cruncher. Once on the endangered species list, code-crunchers have Commercial Three Bayliferated at an exponential rate not unlike rabbits. They're everywhere. They're everywhere. The commonly held belief among code-crunchers is, if it doesn't have a code it can't be fixed. I even had a caller on my radio show the other day who was told by a code-cruncher that he couldn't diagnose whether or not the thermostat in the caller's car was bad because there was no code in the computer.
WHAT? Are we all condemned to driving cars that don't run right, don't steer right, have myriad illuminated warning lights just because there's no code? Hey I like the concept. It means more work for me. Job security you know.
Anyway. The module you're looking for is located in the compartment behind the driver's seat. Lift the carpeting, remove the single retaining screw at the front of the compartment lid, examine the wiring, if nothing physical can be seen, disconnect the battery, unplug the various wire connectors, treat them with contact enhancer (Stabilant 22A), reconnect them, and 99 times out of a 100 the Commercial Three Bayblem will disappear.

I have a rattle in the rear hatch on my 1994 C-4 coupe that is driving me crazy, it sounds like it is metal to metal. I have tried to adjust the latch and the striker and have also tried to tape the striker and cannot get it to stop rattling.
Now here is the stumper. I either had top off, or had a canvas replacement top on it all summer. I put the glass top (solid), back on it to get ready to store it for the winter, now the rattle has stopped.
Maybe you can help so I don't have to listen to the rattle again come next summer. I sure like having the top off.
Have you heard of this trouble before? What can I do? Thanks.
William A. C.

Answer:
Start by replacing rear hatch window bumpers, then readjust the latch. In some cases you may find it necessary to shim the bumpers ever so slightly by gluing very thin rubber to their top sides. Be careful. Be very, very careful. Too much shim and it's goodbye hatch glass.
Pat:
Could you please tell me what seats if any would replace the seats in my 1986 Corvette and be a direct bolt in?
I hate the bolster and would like seats without them or be wider or something or be without them completely. I have the sport seats so if the replacement seats do or don't plug in it doesn't matter.
Also, could you give me a place to go for them and an apCommercial Three Bayx. price?
Question 2. My 1986 Corvette with the 350/230 cast iron head motor/automatic trans, after sitting for a few days or maybe even a week or two starts "immediately" when I turn the key.
But when I attempt to start it more than once in the same day or even on consecutive days it has to crank (which seems like too many times) a few times before it starts.
Could you tell me what or why this happens and how could I make it start faster all the time?
Question 3. In reference to your answer (Oct. Mailbag) about the ABS brake system recall for a master cylinder piston kit on 1986 Corvettes with serial numbers between G5100001 and G5118892, my local dealer ran my serial # (which is between the aforementioned #s) and he came up with nothing.
He gave me a phone # of someone at Chevrolet customer service. In speaking with them, they too came up with nothing. She said because it was so old (the recall was in 1986 according to her), she wasn't able to get much info or a hard copy. She asked if I had the recall #, obviously I don't so I was wondering if you have it or any other pertinent info I could Commercial Three Bayvide them.
Thanks in advance.

Answer:
I can't help you with the seats. I have never been quiryed about less bolster, only for seats with more/better/more supportive bolsters. Most Corvette drivers want their butts help firmly in place to better enjoy a Corvettes amazing cornering capabilities.
Sorry.
Long crank times? Check for fuel pressure leakdown Commercial Three Baybably due to dirty or failed fuel injector or injectors.
The recall number is: 86C12 dated 860901. See opening letter - this column.

I have a 1971 Corvette with a 454/365 hp/auto. I've owned the car new (1970) and had the engine rebuilt to stock specs in 1990 ---- only 4000 miles on it. The car has always run strong and relatively trouble free.
Here is the Commercial Three Bayblem --- last weekend I took the car on a 250 mile run. In the first 100 miles, at 70 mph I noticed a blast of dark smoke (dark gray) behind the car that lasted for about 5 seconds --- no drop in rpm or oil pressure and no increase in engine temperature. During the total drive this occurred four different times spaced from10 minutes to 1 hour. There is no water in the oil and the smoke is coming through the tail pipes.
Since the car does not go for many long runs I was wondering if it was carbon blowout, but my local garage feels it may have something to do with valve guides or oil rings on the pistons.
PLEASE HELP!

Answer:
Careful. I think you're overwidgeting this Commercial Three Bayblem. Intermittent black smoke equals too much fuel. Intermittent too much fuel equals internal carburetor Commercial Three Bayblem. Power valve or equivalent.
Pat:
I very much enjoy your column, I am impressed each month by the extent of your Corvette knowledge. I would appreciate your advise on a couple of Commercial Three Bayblems I am experiencing with my stock 1972 Corvette, 350 ci with auto transmission.
Under acceleration at speeds below 50 mph the car will downshift from third gear to second with no Commercial Three Bayblem, however it will not downshift into first gear at any speed. When coming to a full stop it downshifts with no Commercial Three Bayblem, I may be off base, but I feel the transmission should downshift all the way to first under full throttle conditions when at speeds less than 20 to 25 mph and downshift to second gear at speeds a little higher than 50. I suspected the detent switch. I have adjusted its position with no change.
I have looked in all of the Corvette parts supply catalogs I have and none of them seem to offer a replacement detent switch.
Now for the second Commercial Three Bayblem, when the engine is turned off the wiper cover raises itself and remains in the raised position until the car is started again. Any advise for these Commercial Three Bayblems would be greatly appreciated.
Thank you.

Answer:
If your '72 is equipped with a 350 transmission, check the condition and adjustment of the kick-down cable. If it has a 400 transmission, check the modulator and the electric kick-down switch. If the switch is bad it should be readily available through a transmission shop or Chevrolet.
For the wiper cover, start replacing vacuum hoses. Your car has lost the ability to maintain vacuum reserve. The vacuum system is no longer airtight. The hoses are available in kit form from Mid-America Designs.

I just finished reading the November issue of "For Vettes Only" and would like to add a few comments to the letter on C-5 nits.
I drive (everyday) a '98 convertible purchased new in early '99. The car now has a little over 170,000 miles on the clock. The transmission (automatic) was replaced early in the game and other than that I have had very little trouble with the car.In fact far less than with my '93 which had constant brake Commercial Three Bayblems.
Regards,

Answer:
That's a lot of driving. I'm seeing many C-5s with high miles, never ending nits but very few with major Commercial Three Bayblems other than once in awhile like yours, the transmission.
Hello, I received an NCOA newsletter yesterday and wish to get on the chat line or give Mr. Goss a question about imCommercial Three Bayving performance of a '76 that I currently own. It runs well.
My question is, is it advisable to convert the exhaust system to a true dual system somehow or are there other things that I can do to imCommercial Three Bayve performance? I believe the Vette is set up for California standards. I live in Illinois.
Great publications!!!!!
Thanks.

Answer:
Well allrighty now. Do you have an emissions inspection Commercial Three Baygram? If so, do they check components? I ask because, under Federal Law it is illegal to modify any portion of an exhaust system ahead of the catalytic converter. In reality it's illegal to modify exhaust systems . but no one pays attention to lower restriction cats and cat back systems. That combination will give you a slight performance imCommercial Three Bayvement.
Unfortunately there's only so much that can be done with a middle 70s engine. Your best bet would be to open up the exhaust system and purchase a 350 crate motor or a 383 stroker. You'll be legal and you'll have serious performance.
Pat:
I have a 1985 Corvette that I believe needs a mass air flow burn-off module #0-280-215-001 (BOSCH). I am having trouble locating a used one and the price is very high for a new one.
Can this burn-off module be changed to a more efficient or better method without creating other Commercial Three Bayblems?
Also, I'm looking for a used hard top to fit this 1985. Color does not matter, as I will paint the vehicle.
Please let me know if you can help me. I have included my phone # and email address.
Thank you.

Answer:
Wes I'm disappointed! Why would anyone think that $921.00 for a part the size of a flashlight battery is expensive. Sheesh!
1985 only. Special order only as a new part, impossible to find as a used part; even if found a used one has maybe a 2% chance of being better than yours. Perhaps all is not lost though. I spoke to Jerry at Corvette Central who swears on his great-great-great grandmother's false teeth that his part number #304461 for $279.00 will work. Give him a call at 800-345-4122.
I have not tried this and if you do and it works, please let me know.
For your hardtop, start scrutinizing Hemmings Motor News.
