I had a slightley high idle (1000-1200) that i couldnt figure out....went through all the usual procedures to no avail....then decided to clean my battery terminal and found a battery wire that had abroken internal conection, fixed this and solved the idle problem, I suppose the bad wire cause a higher load on alternator..but not all the time, hope this helps somebody else

A higher load on the alternator would not cause the engines RPM to increase. When you unhooked the battery cables, you would have erased the ECU data, thats all.

Part of resetting of idle is to erase the bad gremlins from ECU by disconnect of negative terminal for 5 minutes. Clean air bypass valve and throttle body. Unknown to you, what happened was a electrical exorcism. Bubba

the fluctuating load did cause it to be sometimes high, sometimes not....the ECU was reset many many times trying to get it down through the normal methods such as resetting base idle, TPS, cleaning TB etc, etc etc.....the idle did not rectify itself until ( a week later) I repaired the battery cable

...the very first thing I did initially was to disconnect power for 30 min. as recommended

The only asspects of an engine that will raise the idle is the PSPS and well as the AC and Defrost.....

There is no sensor on these foxes that tell it to idle higher due to electrical loads. If you look at your volt gauge when your have the blower on (not for a/c), turn signals and such at the same time, the volt gauge will drop and it does not increase idle. The charging system will use the battery if it can not support the electrical demand.

Glad to see you were able to fix it and I appreciate you posting a solution to your problem. It will help the next guy who does a search and reads numerous threads that don't have a final outcome.

exactly my point....with faulty battery connections it cannot access the battery
