P2285

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???

I would double check that the harnesses to the FICM are 100% seated. When I put in my BPD FICM I didn't have the harness closest to the firewall 100% seated and it threw the same code. Seated it, cleared the code, and no more problem.

I'm getting an icp intermittent code but I just replaced the d@mn icp sensor less than a year ago. I might mention my icp is on the back of my motor.
