Might be worth testing them to make sure they're all up to the specs listed in the TSRM.

i got the truck running well. only problem i am having now is idle.
the rpm will go up and drop repeatedly, if i step on the gas, it will just go to a higher rpm and drop. if i hold the gas pedal down or step on it suddenly i can hear the afm sucking air but it starts to die as if there is no fuel. i replaced the tps and cleaned the iscv. although, i unplugged the iscv while the truck was running and it didnt change anything. is it as simple as needing a new one? i tried another one i had and it did the same thing.
