| NOTE |
| Replaced IAC with a used unit that was clean inside as the one removed. All three IAC I have on hand are used and present the same resistance.
The IAC I removed was unable to maintain idle as the engine warmed. It has been a little fussy. So I imagine an issue with the solenoid electro-magnet. The 6-year old TPS was fine yet I readjusted it, linkage was fine and I re-lubed the socket ends, TB valve (bushings) are fine, as are grounds and harness connections.
Yet the replaced IAC restores a rock solid idle better than before. |
