Hi,
A plugged fuel filter will cause these symptoms. Also a plugged air filter.
If the filter has been changed then the turbo and all related connections need to be checked, If problem still persists the one must check the injector pump.
Good Luck,
WAYNE

2001 exaust smokes at times engine runs good no missfire running 10-30 motor oil


Exhaust smoke is not a good thing, it can slowly destroy the catalytic converter. The color of the smoke is important to know, gray smoke is usually oil burning and white smoke is coolant.

Cylinder number one stops firing, and black smoke comes out of the exhaust. I replaced the coil pack and spark plugs. when i unplug battery and reset the faults, it drives fine for a couple days. what...


honestly it sounds like you have a bad computer. there is a constant 12 volts going to each fuel injector and the computer momentarily grounds each fuel injector to activate, the black smoke is from too much gasoline and the missfire is probably from the injector either hanging open or being held open electricaly. next time it starts to missfire on number 1 cylinder try taking a stethiscope or long screw driver and put it on #1 fuel injector with the engine running and see if you hear a clicking sound. If not try unplugging the #1 Fuel injector. this won't fix the missfire but you can see if the black smoke clears up. if the smoke doesn't clear up with the injector unplugged and you are sure its # 1 cylinder thats missing, replace #1 fuel injector.
