The truck backfires, sputters, hesitates, and stalls. I have replaced crankshaft position sensor, PCM, spark plugs, wires, and distributor cap. Compression checked good. It throws no codes. Local dealer was not able to figure it out. No on can figure it out. My next step might be to have the wiring tested.

Hi and thanks for using 2CarPros.

Has anyone checked the coolant temperature sensor? Was fuel pressure tested? Was the catalytic converter checked to make sure it is not plugging? Have all grounds to the engine and body checked to make sure they are clean and tight?

Take a look through this link and let me know if there is anything I mentioned or is listed in this link that has not been checked.

Let me know,

Joe
