Geo Posted February 27, 2010 Share Posted February 27, 2010 (edited) So I have been having a few issue's with Idling, car dying when started, erratic idle, low idle, high idle (I am getting high idle and car dying after initial start up, I have to feather the throttle to get round it). So i thought about starting to track the problem down. I spoke with a few people and the conclusion was that it was probably a sticky ICV. So here is a small tutorial on how to remove and clean it on a TT(Single Turbo) Tools Needed: Carb Cleaner Philips Screw Driver Flat head Screw Driver 12mm Socket, with extension and ratchet Long Nose Pliers Swear Tin Plasters Location of ICV So first off was to take off the plug connector, kinda fiddly as its been on for 15 years, take care pulling it off. Next take this pipe off by unclipping it and pulling off, this gives you more room to play with. Nex step is to take off the coolant hose or small K&N filter that I have got since im running a Single Turbo. This will expose a nice shiney metal pipe. Seen here by the red pipe. Next remove the 2x12mm bolts that hold it onto the throttle body, with the rachet, just be careful you dont drop them like i did, took me ages to find the thing. There is also a metal washer the shape of the unit DON'T DROP THIS. you then can pull the ICV up for some leverage to expose the 2 small coolant pipes. These have little clips on them that are very fiddly, just have patience and use the long nose pliers to get them off. HAVE FUN HERE!! took me a while. Next unscrew the philips screws, one Idle Control Valve split in two Use the carb cleaner to clean everything out so that all the crap runs out. Use a soft cloth/rag to clean the actuator (the small black nipple with spring in it). Leave to dry for about an hour. Then re-install after its all done by going back through this in reverse. If it doesn't help your idling problem then its a new one required. Before cleaning After cleaning P.s dont clean it in the kitchen like i did, the bird wasn't happy! O Well!!! Supra's Rule. Hope this helps Guys. Edited March 5, 2010 by Steve (see edit history) Quote Link to comment Share on other sites More sharing options...
