erratic idle on start-up, '99 3.4

[crazy Jim]

Starts rough but clears up after about a minute, I'm assuming the IAC is sticking. Whats the proper procedure for dis-connecting and removing then cleaning and re-installing? thanks

Turn car off and unplug the IAC from the car. Remove and spray with carb cleaner to remove gunk. Reinstall in reverse order. Do not move the pintle while it is out or you will have issues. Plug back in and start car. Should clear up the issue.

Could also be a vac leak.......coolant leak into cylinders(misfires until coolant is eliminated).....fuel problem.....etc.
