Any idea what to try next? Cleaning, then replacing the IAC didn't phase the problem, P0307 literally within 2-3 miles of clearing it but -ALWAYS- occurring at low RPM.
If I clear the code and then watch my RPMs close, kick it into neutral before coming to a stop and maintain idle above 1000 rpm it won't occur and the truck runs smooth as silk all day long.
I'm about ready to take it to the dealer, but am hesitant to at this point because I'm afraid they may want to re-do everything we've already done and charge accordingly.
Thinking more about this, in retrospect I honestly believe this problem, all the way back 18 months or so when it initially started may have always been occurring at low RPMs, but I didn't pick up on that until we SAW it doing it in the shop a few weeks ago.
I'm also beginning to question now if when I swapped injectors if there's a chance I mabye got 'em mixed up and put them back the same way they came out. (Dyslexia runs in the family) So I guess the question here would be if it is at all possible for this to be an injector problem yet only show up at low idle?
Thanks!!
