Fuses all good, harness (as much as I could inspect) looks ok, no vacuum line or fitting leaks, but found the air intake box was not set correctly. Re-set this and truck runs fine except warm idle. Idles fine cold, but as soon as RPMs drop upon warm-up it stalls. Some accelerator (above 1200 rpm+/-) will keep it running smoothly.
I cleared the codes and no new ones are indicated after keeping the truck running.
Would this narrow it down to the IAC? Reminder – new battery was just installed.
have the same problem?
