|  Intermittent high idle
Every now and again, my idle decides it wants to be at 1300 instead of its normal 750 or so. I've tried to kick it down, to no avail. I'll shut down for a bit, restart, and it'll be okay. The TPS reads .539. All vacuum lines and wires look fine. Any thoughts? | ||||||||||||||||||||

Hi ChuckG, Ah, those intermittent issues... Did you verify the operation of your IAC ? | ||||||||||||||||||||

It was verified as good in mid-June by C4C5 Specialist at Mid-America's Cruisefest (a GREAT event!) and I don't expect anything has changed there, but maybe? The unit itself is about three years and 7,000 miles old. I'll recheck and verify the wiring is good. This began about the same time as I changed to Gen III injectors. They're still 24lbs, so I think that's coincidental. | ||||||||||||||||||||

New info: Noticed today it's generally when the car is restarted warm this high idle occurs. It will not kick down and lasts until I shut down and later restart. | ||||||||||||||||||||
