91 Camaro if its not the mass air flow sensor do you have any other suggestion on what it could be?

Question moved to Chevy Camaro.

I'm GUESSING... fuel pressure regulator<?>.

No, you have a map sensor

I don't believe this year model uses a mass air flow sensor, but a map sensor . but to clean a mass air flow sensor, you have to remove it from the sensor housing, then look at the wires in the sensor, then take a cotton swab with alcohol on it and very gently rub the wires with it.

EGR wouldn't do it. Thinking mass air flow sensor of intake air temp sensor,no codes?
There is no priming injector on that ,it just extends the pulse width of the 8 others,
Have to scan it ,see if the manifold air temp is right,possibly just clean the mass airflow hotwire with spray cleaner,if you pull the maf and look at the little wire in the center,if it's coated with a white substance ,try cleaning it .Same with the manifold air temp sensor.

is the sensor new?
check the wire from the very root of the air mass sensor wiring to the sensor its self.

it sounds like either the air mass sensor is at fault or the wiring is touching somewhere.

I have a 95 Trans Am myself, with a worked 383 lt1 with full bolt ons. etc Your using the factory tune with that setup? While the check engine light might not be on because of the factory tune i would strongly suggest at the least, getting a mail order tune, and if you can, a dyno tune. You're not seeing the full potential of your setup the way it is now. Are you using an aftermarket mass air flow sensor? The stock mass air flow sensor flows plenty for most setups. Aftermarket sensors can cause driveability issues and many suggest staying away from them.
Are you able to scan the computer to retrieve the codes? It's impossible to diagnose the check engine light without knowing why it's on.

Its located on the air cleaner box (the box where your air filter is) Its had cylindrical shape and kinds square on the top its black in color and had a plug on it. There is rubber intake hose connected to it. Good luck and thanks for using Fix-ya

could be map sensor or mass air flow sensor.
