hey guys, I just recently studded my truck and installed some 175/75% injectors... It started Great!
Only problem is I am getting an ICP circuit code... (P2285) and my exhaust tone pulsates while driving down the road... The boost gauge will actually show a 1-2 PSI pulsation while driving. The pulsation seems really noticable when I'm giving it steady throttle, like when I'm going up hill or on the highway.
What could this be
PS I got all the air out of the system... real good lol so no air in the oil rails anymore.
I am thinking...
ICP sensor? (but it was good when I shut it down)
Wiring? (wiring plug coming to the FICM)
PCM? (When putting batteries back in, I sparked the power with a ground)
Does the PCM have anything to do with this???
