Idle

[shadowracer]

You know what, do this, First off I'm assumming you know where the IAC (Idle Air Control Valve) is located. Right? Well check the electrical connection first if there is any corrosion in there clean it out with a good electrical cleaner and a small wire brush. Second check to make sure your vacuum and coolant hoses are not leaking. Coolant is easy do a visual and if you can't see it rub your hand on the hoses. Make sure there not hot! FYI ! You can check for a vacuum leak by spray starting fluid by the IAC if your idle surges then you have a vacuum leak present. Third make sure your coolant level is full the IAC use the coolant temp to determine the IDLE speed. (that should have been first,whatever) If all checks out take to the dealer and shell out the cash
