Re: 5.3 Gen 3 - Misfire/rough idle
Was it tuned for the cam, need to know which cam too. Just "stage 3" doesn't help as BTR sells 3 or 4 cams with stage designations. It most likely will have a lot of chop and a rough idle regardless. The first thing is to tidy up the harness, a new one, rework what you have, something. Crossed wires, poor splices, and bad grounds will wreak havoc on the system. Coil harness' not plugged in right or fully are a common problem as well.
