I had the codes read today and had a misfire on cylinder #5 so I switched the coil pack to cylinder #4 and reread the code and #4 was misfiring so I ordered another coilpack. Will know tomorrow if it solves the rough idle. If not then I will get a compression test. The PCM update what is that all about...?
Hey! Well after cleaning the throttle body...fuel filter...plugs...cleaning injectors with seafoam..airfilter...and MAP sensors I narrowed my rough Idle and Acceloration down to one bad coil pack! Replaced it and CEL is off and TB is running like NEW!
Again thanks to Trailvoy and all its members I was able to solve my problem!
