Went to auto store to read codes and the PCM determined that multiple misfires have occured in cylinder 1, 3, and 5.
Also, the fuel system for bank 1 was too lean(location of cylinder 1)
All probable causes for misfires. :
1. Ignition system fault-spark plugs, ignition wires, coil.
2. Vacuum leak
3. Injector fault
4. High or low fuel pressure.
Probable causes for fuel trim bank one:
1. Mass Air Flow Sensor (not it-mechanic tried)
2. O2 sensor
fuel injector problem
My car was running fine before I brought it in to change the spark plugs. Had NYS inspection done 2 days prior and there were no lights on. So is my car jerking as a result of the spark plus being installed incorrectly? Thanks
