[QUOTE="Brickman, post: 1080903, member: 14965"] So I give up. So far I have replaced the IDM, the IPR, the fuel pump, the fuel filter, battery cables, and the CPS. Truck still is hard starting and has a heavy miss on acceleration. Passes the cylinder contribution test and all other test with AE. Number 3 is a little week on the buzz test but they all sound good. No codes other than ones I have should have due to gutted AIH and EBPV. Pulled the ICP and still hard starting. I have attached the AE file from today. You can see at very first in the graph a large spike. This is when the truck started. I also have misses when it accelerates. Mark [/QUOTE]
