Does anyone know how to fix this. P003a turbo charger boost control not learned? just installed finer and blocker plate?

Uninstall the finger module and verify the operation of P003A. If it cleared, figure out the wiring before the re-installation of finger.

X2. I think there is something screwy in your fingers stick wiring.

I will check it out.I had a disesel shopm install it all for me. The wires were all color coated? Afterwards the truck ran fine for a few days after the install. Is is common for it to mess up like this a few days later?

are your connections soldered? Not good to have intermittent connections. Best connections under the hood are soldered.

Yes, they are soldered. The truck will idol fine for awhile but when you hit the gas it starts to flutter.

Is this a dealer issue?

Got it fixed today. (turbo vein sensor)
