Rough idling no power. Mild black smoke. I set the timing at 10° btdc. The following parts been changed. MAF, IAC, TPS. All the wirings from sensors to pcm been checked and found ok. All fuses are ok. Intake manifold gasket is new. Fuel pressure is 50 psi fuel filter is new. I tried to removed and put it back the maf sensor wire but the engine idling the same. It seems that the maf sensor is not functioning. Snap acceleration it backfire
have the same problem?
