1994 gmc k1500 Sierra sle 5.7l engine codes
I have a 94' gmc k1500 sierra sle 5.7l witch has
recently been rebuilt due to blown head gaskets.
All the timing is correct, all new sensors yet I keep
getting code 32,42, and 44. After start up the truck
idles fine, its once i get rolling is when the issues
start. About 2 miles into a drive the check engine
light comes on and it seems like the engine doesnt
have the take off power it had 2 miles before that.
Also at low speeds of 15-45mps it has a ruff time
maintaining speed. Please help
