Hi all, New to the forums. I have been searching the forums and haven't quite been able to figure out my issue. I just finished with a plenum pull. Now i have really bad loss of power and also white exhaust smoke under acceleration. Additionally i have intermittent back firing. I did not have any of these issues prior to plenum pull. When the plenum was off i did valve cover reseal, erg bypass, pcv delete, coolant line bypass, new connectors on both coil packs and injectors. I replaced the spark plugs less than 1k ago. Im running out of ideas. Does anyone have suggestions of things to check?
