I have noticed it putting when in idle and engine light came on. Detected random misfire, changed all 8 spark plugs and noticed cylinder 8 had oil on the spark plug. when started code read cylinder 3 misfire, replaces 3rd spark plug. Still getting 3rd cylinder misfire. Should i replace the wires to the plug or should i try and relive the fuel injector?
