[oneofmy3]

In need of help again guys...

Truck has been running ruff,lack of power,missing,just different. I have replaced icp, cps(3 times),and tested all injector ports on valve cover plugs with ohm meter.all checked out good. Had my dad bring home scanner passed buzz test then I did a cylinder contribution test failed cyl 3,4,7. Also gave me a code for bad air intake temp switch,and cps.

Replaced both of them two weeks later re scanned--
Code for Internal control modgel KAM malfunction. P0603

Did buzz test passed but got code for IDM (ignition Diagnostic monitor malfunction). P1298

Did CCT. Failed cyl 3,4,5,6,7

P.s. I had a chip in my truck that us acting up so I removed it two months ago,when I went to remove my computer from truck it was rusted in place. The computer is in bad shape, looks like I left in in a salt mine for ten years!



Once again, thank you for your help
