ya i went to the dealer after i changed the engine and they did a relearn but it didnt change anything.

 

I'm kind of at a loss. The only things I can think of is that the pcm isn't programmed to your vin and the knock sensor. Sorry, hopefully someone else will chime in.

 

Well i never changed the PCM and the knock sensor i transferred over from my old engine, but i did notice that the truck my new engine came out of calls for a different knock sensor part number. So im curious should i have used the knock sensor that came out of that truck or the one from my original engine?
