Replaced Cyl 1 and 3 Injector a couple times, Replaced the cp3 pump, return lines, lines on the injector, fuel rail, did the update tsb.
Some times it has a fuel knock at idle. The check engine light seems to come back at idle. Swapped pcm's Kind of lost.

Did you flash the new injector codes into the pcm?
