Hi. I have been having on/off car problems with my 1995 geo prizm since Septemebr. It would shake, lose acceleration, and stall at stop signs or red lights. I had distributor cap, rotor, spark plugs, and coil replaced. Used fuel injector cleaner. I had two mechanics check out the car and was finally told I need a new computer system. A mechanic upped the rpm's for me and the car was fine for two weeks. Today, it would not start and I had to jump the car. A friend mentioned that a bad a/c compressor clutch could cause the symptoms my car was having- stalling, chugging, etc. Any advice? Thanks.

Could be caused by one of the following below

Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.

Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard it and keep testing.
