1990 pontiac sunbird cutting off if not constantally getting gas

I am losing my mind over this one. When driving i have to two foot this car. You have to keep on the gas when at a stop. Sometimes when the car first starts it will idle but high. Then it cuts off. When driving, you have to keep giving it gas, put in neutral when stopping or it will shut off. I have changed the fuel pump, plugs, wires, control module, tps, etc.. The weird thing is that when i changed the control module, it ran perfectally for about 15 minutes! Then went back to shutting off. Sometime when the car is first started, it will have and extremely high idle then after hitting the gas a few times, it comes down. When driving sometimes it feel like it is losing pressure other times it drives jerky. I have changed the air filter and notice that it has been soaked with gas. i love this little convertable and want to keep it. Help.

I have a 92 pontiac sunbird that when I try to go fast it doesnt want to go like I press the gas all the way down and it stays the same speed it does not accelerate when I step on the gas? Help

Check the catalytic converter if front of muffler....When they get clogged you lose power. Unlawfully you can cut it off and straight pipe. Don't throw it away...They bring a pretty dollar!

My sunbird is losing power while im driving. Check engine light comes on and off. After losing power, it starts up then loses power when accelerating and cuts off again. I had the head gaskett replaced

sounds like the distributor, I would replace it and see if that fixes the problem. If not then it may be with the fuel pump and filter. Good Luck Tim

Car stalls out while running

It sounds like it's not getting enough fuel to the engine if it stalls when you let up off the gas pedal but stays running with your foot on the gas it sounds like you need a new fuel pump and or fuel filter for the car.I can almost garantee thats part of the problem
