I'm having a problem with my truck after swapping the PCM. It was running fine on the old PCM now the long term fuel trim on the drivers side is at 14-20% additional fuel but the passenger side is running at -4ish. I also noticed that I can't shut off cylinder 2's injector so it could be stuck. I'm just wondering if someone has had something like this before or know what could possibly what could be going on?
