Also, pump the brake pedal before detaching battery cable. Will eliminate
any residual electricity.
Was reving up to 2500 consistently until I applied the above technique.
Idles like a charm now.
Go figure.

That is basically forcing the idle relearn. I can't imagine it takes hours. I've gotten the idle to relearn with just unplugging the negative cable for 15 minutes. I turn the lights on and hit the brakes, then reconnect the battery.
- Let the car idle and get up to normal operating temp. I wait until my fan comes on in the summer months.
- Then wait at least 1 minute after reaching normal operating temp.
- Turn on the AC to Max and let idle at least another minute.
- The turn off the AC and go for at least a 10 mile drive. I usually cruise around for 10 - 15 miles, then do one or two WOT's. The computer will still continue learning idle, but you should notice a big improvement from when you first started it up.
I do this any time I change my tune, or when the mechanic I go to disconnects the battery for any reason.
