Default RE: idle problems

You can start by cleaning the throttle body with carb cleaner. Just remove the rubber air intake until you can get to the throttle body with a can of cleaner. You should also remove the IAC valve and spray it out good. Just make sure you have a new gasket or dont damage the old one. Try one thing at a time though so you know what the problem actually was.
