So ive had a loss of power within the last week and i pulled all of the plugs from the coilpacks. There was one that didnt idle down so i pulled the spark but doesnt look fouled out. I ran the ecu for any codes and got 55. So its not an injector issue because that would show up on the ecu diagnostics right? I switched a coilpack from my old n/a engine and switched them out. Put everything together and pulled the plug on the coilpack and it stayed the same. Could it be that connection?
