RE: SURGING IDLE ??
A bit more information; THANKS to mjhenks who posted this in the General Tech section. He read thru these links that Desert posted, & wanted to add his experience...
They suggest checking the water passage on both theIAC Valve and the Fast Idle Thermal Valve. (FITV) Both of mine were "open" but i decided to check inside anyway. Good thing I did. I found that my IAC exit water port was nearly blocked andthe FITV hadcrystallized inside its water passage.(It had a build up of mineral deposits) Once I cleaned all this out my surging idle problem went away. So I would recommend that you take the water passages apart and clean them. Youwill need a tri driver and some silicon to make a new seal for the IAC.
