Engine Performance problem
1989 Chevy Camaro 6 cyl Manual

I am having trouble with my camaro, it turns on very well but the problem is when i step on the gas pedal. What happens is that the car kind of chokes and loses power. I have already replaced spark plug wires, fuel pump, ignition coil, fuel injectors, alternator, timing chain and sprockets, distributor cap and rotor, temperature sensor, water temp. sensor, battery and terminals. I thought it would be the idle setting but when i checked under the hood the label read that the screw was factory set and adjustments should not be attempted. please help...

More likely the Throttle Position Switch on throttle body. Also clean throttle body well.
TPS on throttle body transmits throttle plate angle to ECM. Chech it out let me know

I replaced the sensor and after ignition the same problem occured, I lightly stepped on the gas pedal and the engine wanted to turn off but once I released the pedal it went back to normal.

I cleaned the throttle body, the MAF sensor was replaced by the previous owner and is in very good condition. If I just floor the pedal the engine will completely turn off, but it will turn on just fine after I floor it.

It does have a new ignition control module, I have decided to take it to a chevy dealer first to see if they can find the problem, thanks for your help.
