My AAC valve, which controls the warm idle, is history. It does not ohm properly and even after rebuilding/cleaning it I still have a searching idle. While ohm testing, I would get a flash of a reading, then zero. Then it would repeat. This is my indicator of what is happening with my searching idle. If anyone has one that is good, works properly, and ohm checks correctly I would like to take it off your hands. Email me with your offers if you are looking to get rid of one. motrsprt at cableone dot net
