When the lite is on the engine runs on a set of specs. When itis off, the computer controls the mixture. Have the codes read and repair what is causing the light. Does this seem to happen at different times? Does it seem to happen when you attempt to start the car after it has reached operating temp? Does it just happen when youslow or stop for a light and stall the engine? If you say yes to any of these questions, it may be the cold start sensor. This was a pretty common problem when the car first came out and had GM baffled for a while. Replace the sensor and it should fix the problem. The sensor acts like a choke whencold, giving a rich fuel mixture for cold start. When it goes bad, it gets confused and will give a rich mixture after the engine comes to operating temp and flood the engine. To start a flooded engine, take off the top of the air cleaner, unplug the injectors, start the engine and burn out the fuel. Just before the engine stalls, plug in the injectors and the computer will reset for a while and the car will run fine until next time the sensor gets confused.

Check the fuse box in the engine compartment
.The check engine light can be reset, after you install a new air intake, by removing the instrument panel fuse. The fuse can be located in the fuse box
Causes for the check engine light to come on in a 1981 Chevy Corvette include overheating, low oil pressure, and a bad alternator. Because this car is not equipped with a computer, it has limited self diagnostic abilities.
Yes
check your sensor on the back of the engine block and under the intake manifold, passenger side. check your sensor on the back of the engine block and under the intake manifold, passenger side.
Not normally.Not normally.
check the battery and connections/cables
I had the same problem. Took it into the dealer and it ran me about $1,000. Blown head gasket in my intake. In other words, this car is no Corvette, lol.
Need to check the 4 corners on the intake manifold. It is common for the intake to leak engine coolant.
it could be an issue related to your oxygen intake check oxy sensors if check engine light is on.
