    engine misfire on cylinder number 4

  • Anonymous Mar 23, 2014

    Hooked up to computer at auto parts store and read 92 sensor for #1 cylinder bad. Changed it and engine still shakes while idling and while driving. Engine seems to run fine though, did not change plugs yet. Thought they burn out when sensor was bad. Anyone have this problem that has answer to a fix? This on a 96 FORD EXPLORER XLT 4.OL engine.

From Lusty Kid:

I know the economy is bad, but change all of the plugs. Check your PCV Valve hose, 150 rottens them out allowing air to be sucked in, thus all kinds of codes.

Depending on mileage. Dismount the EGR valve and clean passages. If you are really good dismount the throtle position sensor body and clean out passages with Choke Cleaner., dismount where the EGR valves connects to the engine, clean out passages. Also check the hose thats behind this mounting to ensure is not clogged. If clogged clean it out. If not replace it. Is about 1.5 ft. long, connects to the PCV Valve Hose.

When is the last time you change your harness. Can't remember??? Replace it. Good Luck

All those codes are the same BASIC code just for different coil pack secondary. You need to check the wiring from the coil packs and make sure they are all grounded properly.

Auto Systems and Repair

Ignition Coil "A" Circuit Primary/Secondary Malfunction Our emissions expert has put together the following information about the P0351 fault code. We have also included diagnostic procedures you can take to your repair shop if the mechanic is having difficulty analyzing the code.
OBD II Fault Code
  • OBD II P0351 Ignition Coil "A" Circuit Primary/Secondary Malfunction
What does this mean? The ignition coil or coils are responsible for igniting the air/fuel mixture inside the combustion chambers. Without reliable performance from the ignition coil(s) the vehicle will stumble and misfire.

  • Engine idles rough
  • Engine misfires on acceleration
  • In rare cases, the engine may not exhibit noticeable symptoms

  • Carbon buildup in the Throttle Body air passages
  • Defective Idle Air Control Valve or Electronic Body

I get the code P0361 on a 95 Buick Regal 3.8


P0361
Ignition Coil K Primary/Secondary Circuit Malfunction

ALL P0xxx codes are universal for ALL OBDII - equipped cars
(every car sold in America since '96 model year; and a few mfr's prior to that).

If your '95 is OBD-II, that's the code.
BUT, yours *might* be the same goofy "OBD-I.5" that GM put into '94 & '95 GA's; those sockets aren't OBD-II compliant, and God may not even know those old codes.

BTW, codes with P1xxx are manufacturer-specific.

The P0xxx codes can be found at:

Good Luck

If the engine seems to run fine over 1450 RPM maybe there is a vacuum hose leaking or EGR valve is slightly stuck open. Any help from the OBD II trouble codes? Or is there simply no MIL and no stored information in the OBD II computer read at the local parts store through the connector by the drivers knee?
