I replaced head gaskets on 2004 dodge dakota. when started it ran rough and lacked acceleration. Code P0300 and o2 sensors showed. replaced all 4 O2 sensors, but still rough idle and code P0300


That's Random or multiple missfire code. Have you checked for proper fuel pressure? Improper fuel pressure will trigger this code if it's too low, thus causing a lean mixture in multiple cylinders.

PO304.Code means there is a miss fire on cylinder #4. That is what they call a generic code for all manufacters, It mostly has to do with a bad Spark Plug or Spark Plug Wire on cylinder #4. Or it could also be the coil pack going For that cylinder, Depending on the mileledge on your car. End if it is (Abuse)

if you haven't try getting new dis cap and coil wont hurt to replace anyways and a plug wire will arc off other plug wires and cause miss fire may try replacing wires as well.Hope this helps, Good luck

2001 MPV Runing Rough at Idle & low end Throttle


the lean condition is the big clue here it indicates a lack of fuel which is causing the mis-fire on #3. I would suspect a fuel injector is clogged or not getting a pulse from the PCM. ( pulse is the electronic signal)

Miss firing


could be a wire crossed, or it's out of time. since you used motorcraft plugs, did you set them properly to the correct gap? replacing plugs without gapping them can cause the sluggishness, out of time can cause the mis-fires and rough running.
