Check engine light

only if they are obdII which most of the c4s are not. some 95s may have it but in 96 is when they changed over to obdII.
if you jump the a and b terminals on your aldl plug you have to count the flashhes of the ses light. it starts with 12 which is the computer check when you first enter diagnostics. one flash and then two quick flashes. then if any codes are stored count the flashes in the same way and then look up in service manual.

I've never had much luck with AutoZone where I live.  But I could give you the name of a great mechanic if you live in the Phoenix area!

rita, you have a 96 if i am not mistaken so you should have no trouble as yours should be obdII. maybe the help doesnt know how to operate the scanner? try jumping the a& b terminals ans shouls show up on your dash display. many books out there have the codes listed.

Nope, mine is a 95.  Could still be the inability of the associate at AutoZone to get my codes.  I have had someone help me get codes using the method posted.  But now I have a good mechanic and if I mess up trying to do it I just go get him to help.

96 and later would be OBDII. Some late 95s may have it as well. Easy to tell as the older data link is rectangular and the OBDII is trapezoid in shape. I wouldn't do anything without using a scanner to identify the problem. You can buy ones online that do virtually every car model (which is what I use from AutoXray) since 1980, for a couple hundred bucks or some that are for the pre-1996 manufacturer specific data links. These units run about 50-100 bucks. Some basic OBDII units are also available. You ca buy code scanners online or from Autozone, NAPA, or any major auto parts store. Without scanning your car's computer you are just guessing. It literally could be any one of a hundred problem, including something as simple as a loose connector. So, get it scanned or buy a scanner (you'll be glad you did).

If your check engine light was on for 5 minutes don't worry about it yet it could be weather related (i.e. cold, damp, both etc). But as your Vette gets older thing happen. I have been driving with my check engine light on for about 2 years now (91 Model) and running great. However I recommend buying a Diagonostic tester for peace of mind, i have an InNova Tester that handles both OBD I and II and it works great on my vette OBDI and my other vehicles with OBDII. It helps to know what you are facing when you take a car in for repairs also.

Thanks guys. I've drove it a couple of times since this original post and the light has never came back on. No Problems :-)

I have 96 LT4 and mine goes on occasionally. Previously, there was some trash in the intake of the AIR causing the light go on. You might want to check that. So far, when the light goes on, everything seems to function fine. Keep in mind most of the error codes revolve around the emissions systems.
