I have a 1990 Intergra everything is stock, 214k, and I am having throttle issues. When I try to acceclerate car stalls, Im having to pat the pedal to build up speed. If you mash it to the floor it does nothing, I swapped out the MAP Sensor no change. I need help, any suggestions.

 

TPS, maybe.

How is the fuel pressure?

When was the last time the fuel filter was changed? 94
