Hello everybody, I was hoping that you could point me in the right direction. I had a aftermarket lighting wiring harness short under the battery directly to the body.. I had the lights on when they went out and about two minutes later the truck shut down. In order to restart I have to crack the throttle body open and hold it open by hand. Sometimes it will run for a few a couple of minutes up to 2k rpm. It is also running really rough. As soon as I put it in gear it dies. I pulled the code and it has a P0340, I know that there are a few things in this circuit that I may have damaged with the short. At this point I have replaced the CPS. Can any body shed some light on what I should check or replace next?

Thanks for your help
