On my way to work this morning the truck lost most of it's power and struggled to even get up a small grade. Got to work and parked it. Started it back up before i left work and it ran almost like it was an old car idling with a big cam just "loping". checked ICP sesnsor and it was covered in oil as was the pigtail. Bought a new ICP sensor but the pigtail won't be here til tomorrow. sprayed out the pigtail with some brake cleaner and put a little dielectric grease on the new sensor. fired it up and still same thing. hooked up my OBD2 adapter and checked on torque. my PSI on hpop was 650ish at idle in park (600-700 rpm) and 2900 psi at 2500+ rpm in park. I drove my work truck home (got fixed today) so my personal truck is still sitting at the shop. didn't take it back out on the road. I plan to swap out the pigtail on the ICP sensor tomorrow evening. however what else should i look at or symptoms should i look for?
1999.5 F350, 4x4, auto trans, 160k miles, only mods are glowplug relay(western plow), 6637 and well that's about it. tranny rebuilt at 114k with a shift kit (before i owned the truck) Any help would be GREATLY appreciated!
99 F350 (99.5 motor E99 suspension)
Rebuilt tranny (with shift kit) @ 114,000
6637, Foil Delete, IC tubes Boots and clamps cleaned
A) lack of electrical continuity to 'an' injector (inj solenoid, inj wiring, IDM issue)< ie, something electrical
B) bad ICP sensor
if the truck doesn't have a dead misfire on one/more cyls...then it's most likely an ICP sensor/harness issue.
highly recommend using OEM Ford/Motorcraft sensors
Also, you have a constant SES light but no codes? That seems odd. As long as you have a scan tool that will pull Ford enhanced codes, you should be able to pull something from that light. Unless something fishy is going on with your PCM.
