Your car should have fuel injection not a carburetor. The air/fuel ratio is controlled by the onboard computer. If it is running rich, I would suspect an O2 sensor, perhaps a dirty air filter, needs new spark plugs, or even a new catalytic converter. You need to have the computer scanned for trouble codes. The codes will give us a place to start looking for the cause of the rich mixture.

    1988 Chevy Nova uses carburetor and does not have fuel injection. That model is a mechanical car.

    I was thinking of the 1988 Nova Sprinter which used the twin cam engine from the Toyota FX-16, which is a fuel injected engine. I'm not familiar with the carb engine, but I'll see what kind of info I can get on it.

How to get to air fuel mixture screws for adjustment with carb on engine, no room to get flex screw driver to the screws ! This is on a 1984 Ford E-150 van with a 302.


Do you have a Holly on that ? if not then, you have to pull the carb. apart to adjust the fuel/air mix, are you talking about the idle air mix screws, this only adjust the idle mix, not the fuel ratio when running above idle, I have seen slots (screw driver) oval, hex screws, your going to have to see which one you have, take the air cleaner off and reach it from the front of the van.

On the carb you should have 2 screws. One for the air and one for the fuel. You will able to adjust your air fuel mixture via those screws.

My 83 cutlass supreme check engine light on


It means the car is running too rich. Check the air filter. If it clean you will likely need to rebuild the carb if it hasn't been done. If it has you might just need a carb adjustment.

I think you must have the carburettor plunger not going well as you are getting flat spots under sudden acceleration, I think the best way to go is to get the carburettor overhauled.
