no sound?
There should be a repeated clicking sound actually once the car turns off, if there is no sound that that would be your best bet. hmmmmm.. how to explain exactly where it is. well.... usually they are nto cleaned when they go bad they are usually replaced however if you are brave adn mechanically inclined clean it. IT takes about 30 minutes total. Youll need some high flash point solvent, a tooth brush, some professional lubricant oil, and a few minor tools for removel and dissasembly.
The ISC is located near the rear of the intake manifold on the engien side. raned our looking at the car from the front with the hood up. There is a LARGE vaccum line that connects your turbo manifold to the ISC. It is metal. IF you follow the vaccum lines on the rear of the firewall the realy large one will run into it. It is um errrrrr... maybe 3/4 inch in diameter. ITs big you cant miss it. There are 2 bolts that hold the ISC to the intake manifold. There are also 2 lines that run antifreeze to and from it ont eh lower side that are hard to see. (this is to help bring it up to operating temp) Remove the vaccum line, there is a rubber connection, then remove the bolts, adn the lin clamps. There will be several pieces that come out of the intake manifold, apy attention to placement and direction, be careful not to damage the one way diapghram. misspelled..... fuck it.
once you have removed it and are looking at it remove the srews holdign it together and pullit apart. There are not that many peices to it. clean the carbon of the spinner awith the flash solvent and use a toothbrush if it is stubburn (the spinner is black) also clean the diaphram with flash solvent, dont lose the small thin washers. inside the case you will see the bearings and the magnetic sides. do not clean that with flash solvent if anything you want a little lube in there but thats all.
once you have the parts celaned reinstall and listen fot eh clicking sound when the car is turned off. IT is unmistakeable.
I know this is not the best directions possible but give me a break I am trying to tell you as much as I can without looking at it my self. Once you have done it once you will see how simple it really is and most liekly not have to do it again as it does nto occur that often. (hopefully)
Goodluck. sorry no pics but my car is in the shop for major body repairs. Not my fault, some asshole hit my while I was parked changing a tire!!!! damn it.
