Had maintenance done today on my 2001 4Runner by a local mechanic I have had good luck with. Cleaned MAF, T.Body, new plugs etc. Drove home and noticed the idle is up.....to aprox 1000 normally it's 750-800 rpm. Could this be IAC or something ? Is there a idle 'learning' time if the battery was disconnected etc..?
thx

I had that recently after a tune-up. Turns out I had not pushed the vac hose back tightly on to the throttle-opener thingy on the TB. It looked good, but was just resting on the nozzle. Check all your vac hoses and wires again, and also the intake tube connections for tightness. Idle should be normal after a quick drive when batt is disconnected.

Sometimes the IAC gets gummed up after a TB clean. That's the second place to look.

Fixed
Relearned idle. He was able to disconnected something (to relearn) without having to cut power to the computer. Will update post when I know exact info.
