Hi, I just recently bought a 1988 corvette V- 8 automatic with 14,000. It runs great, tranmission seems smooth however, just yesterday I noticed I had some difficulty starting the car. The car would run slightly then stall. To keep the car running I had to keep my foot on the accelerator. Once I had the car running when I stopped at a red light or stop sign I noticed it would not idol and stall again. Usually I noticed the car idols at about 8,000 however, the idol went down to 4,000 and lower until it stalled. I had to keep my foot on the gas to keep the idol up to 8000 and then I never had a problem. The next morning I went out to see if the car continued to do the same thing and found that the symptoms described were not there. The car started right up with no idoling problems. A second thing I noticed (has been rare but nonetheless there is upon starting some smoke coming from the exhaust. This lasts about five second and disappears. I do not see it all the time only on occassion. I hope there is nothing seriously wrong with the car since I just bought it and didn't notice this when I looked at it. If you can tell me what is wrong could you also give me an estimate on how much it would be to fix? Thank you for your time.

Rasmataz, thank you for your input on this. Could the symptoms I described also be the reason for the smoke? Are any of the listed jobs expensive? What range of price am I looking at for repair. Again Rasmataz thank you for your time.

The smoke during an initial start-up could be caused by valve seals.

The idling problem you should start by having the idle air control motor checked out this is the one that suppose to target the idle speed at all times.

Hey man I really appreciate your time and advice. This is the last question. As far as the valve seals I don't notice the smoke all the time could that still be the problem or could it all be realted to the idle control and the car trying to regulate itself on start up. I didn't notice any unusal overheating heating problems with the car or any unusual color to the coolant reservior. I live in NEPA. I'm not holding you to your word as for cost but could you give me a ball park figure on repairing the idle control and valve seals? This will help to be better informed if I have to have this done. Thank you again for your time you have been very helpful.

It depends what color is the smoke -blue, white or black?? Valve seals-will be blue in color, if it is-see below estimates for the seals about 5hrs labor and IAC motor about 1hr/ labor/price
