Answers :

Check the fuel pressure,also change the fuel filter.check the crankshaft sensor,or replace.It sounds more like the tps sensor(throttle position sensor).It is mounted in line with the throttle axle,on the throttle horn.Of course .with out being there and checking I am just guessing.But map sensor or mass air flow sensor could also cause this.Have you checked the air filter?This will cause the problem,if it is stopped up restricting air flow to engine and mass air flow.,map sensor,and vacuums needed to run the car.If I can help,let me know.
