engine light on, scanned it code P2311 comes up replaced the plugs and the coil pack for cylinder#4 as required, hooked battery up and started it, engine light on again, car has rough idle, and bucks and hesitates when going down the road when you give it gas. injector checked and fuel pressure and pump checked all ok. Code 2311 keeps coming up. checked wire harness the attaches to coil pack appears ok. need help not sure what to do. I read on this code also it has something to do with ignition current from PCM which is the computer Brain, I hope its not that.
Codes 2302, 2305, 2308, 2311, 2314, 2317 all on. Run sluggish and cuts out at ~2200 rpm frequently or intermittently
Shows code p2314 runs rough hits rev limiter 2000 rpm changed coil still same it's not the plug or coil what tells coil to fire
With code reader getting p2308 code and misfire cylinder 6 (p306)and random misfire (p300)all codes say permanent. Liberty misfiring to the point it won't run. Replaced ignition coils and plugs. All recommendations point towards new pcm.
