it was on and off since i had bought the car read the computer and no codes are present got a malfunction from the crankshaft position sensor and low voltage on the maf sensor replaced both no codes returned i had also looked at the timeing and it was correct according to the hanes manuel with the proper timing marks alingned but still same problem
Did you replace the ignition module? That is the most probable cause. Otherwise I would clear all of the codes and start the engine. The first code that comes back is the one I would concentrate on.
The other thing that could cause this is the camshaft sensor.
the idi integrated direct ignition module has been replaced and i will look and see if it has a camshaft sensor but i don't think it dose.
no camshaft sensor crank shaft only and it has been replaced
The only thing I can do is list the parts that could cause this. Each one has to be tested manually. Otherwise, I don't know what else I can go to help you. Here are the parts that I have experienced this condition with:
Powertrain control module
Throttle position sensor
Maybe someone else could give input.
The only one that i didn't replace was the tps at a closed position it is 0.35v the Haynes manual states that the closed voltage should be less than 1.25 volts and at 96 % (throttle) open it reads 4.27v
