I got this car and at idle it would be real rough like it didnt know if it wanted to shut off or stay running, I replaced distributor and computer and it ran fine, for probably 3 hrs of driving, then it had the same symptoms all over agian, I replaced idle air control vavle, 02 sensor, fuel filter, and catalytic converter it ran fine again, let it idle for 20 min, drove it 4 miles let it idle some more then it died again, all within say an hour, had no spark, so I replaced coil, and ignition module, ran good for 2 hrs of driving, now im back with the same problem starts has bad idle code reader says map sensor ive replaced it erased the code and still says map, so that code is because of the idle, and when pressing accelerator it wants to die, please please any help is appreciated.

I am not a mechanic at all but I know some things my car is doing the same thing in a way. Um. Check the timing chain. And harmonic balancer. Make sure ur throttle is good to. Like maybe adjust it some.
