Starts fine now. With chip in, give some throttle, throws CEL. Pretty sure for too much HPO.
Took chip out and same thing, give it some throttle, throws CEL. But, cel light goes away at idle if you leave at idle.
I need a tuner to tell me if their tune (s) will tell the computer to expect more HPO than normal or tell the IPR to open more.
For kicks, I swapped the IPR and pigtail and got no difference.
Mechanic hopefully is coming tomorrow to see what his computer is telling him.
I don't think I got a miss but, I could pull valve covers to check oil spouts. If an injector isn't working, that could raise the pressure some I would think.
