[QUOTE="speedracer1000, post: 1432091, member: 2739"] i got an issue with an 03 that i jus cant seem to figure out. im down to swapping out a wiring harness but would like to confirm diagnosis first. i did an engine swap on this truck and used the wiring harness on the engine that i got. same year and all no reason y it shouldnt work... so i get it running and wen cold it wants to do this surging high idle thing right off the bat. wen u try to rev it sounds like its got a big cam in it real choppy and not very smooth. when it warms up it idles somewhat normal and drives better and better the hotter it gets. immediately throws icp codes one is 2286 and 2287 which one is a circuit code and one is signal intermittant. watched icp voltage and it fluxuates bad wen running from .8- 4.0 volts back and forth all around. so i swapped 2 diffeent icp sensors no change.. i put the scan tool on it and watched icp volts its a steady .25 volts koeo and went out under the hood and did a wiggle test and it never moved. swapped the pigtail no change(had been changed already). i swapped another known good icp and pcm from my personal truck with the same results. only thing i think is left is the wiring harness. i thought about cuttin it open to try and find the issue. but i have another harness to swap in if need be. my question is what tests can i do to pinpoint the issue. everything seems normal untill the truck is running. i cant get volts to bounce around with koeo, which kinda throws me off on thinking its wiring related.
