Change the fuel filter and give it a tune-up. New cap, rotor, wires and plugs. While you're at it, put in a new air filter and PCV valve.
Timing is off.
If a 1988 Trans AM GTA hesitates at ideal, check the timing belt. If the timing belt is off, the car will hesitate and die.
More than likely a carb problem or your timing is set too low.
Needs a tune up? Bad timing?
sounds like it could be the timing when it's under a load.
You are flooding the engine with fuel when you step down the pedal, and that stalls the engine. This is probably because your car timing is behind. A good tune-up and adjusting your ignition timing will solve this problem.
Look at the TCC solenoid in the trans is going to be bad.
Mine did this and I found out it was the timing belt that needed to be changed.
maybe bad gas water try some dry gas
Check fuel filter.and air filter then timing make sure tune up is up to date.
it is either the erg valve or the timing is off.
If you have good power when on highway and it only hesitates at low speed or from a stop you have a weak spark somewhere. Possible causes: Needs a tune up Fouled spark plugs Old plug wires Ignition coil about to die improper timing
