e30m3 0 Posted April 23, 2007 I've managed to get my car running ok other than having very high idle, the screw on the throttle body is all the way in. What could cause this. If you tap the accelerator ithe revs drop down but then pick back up. Share this post Link to post Share on other sites
Richie-Van-GTi 71 2 Cars Posted April 23, 2007 try adjustying the throttle stop screw, it may be holding the throttle part open, assume that youve checked the throttle cable isnt holding it open? Other than that ignition too far advanced or an air leak. Share this post Link to post Share on other sites
e30m3 0 Posted April 23, 2007 Thanks for the reply I don't think theres a problem with the cable but you've given me a few things to check Its going for its MOT on Wednesday, they can look at it but i'd rather sort it out myself first. Share this post Link to post Share on other sites
pug_ham 244 3 Cars Posted April 23, 2007 Have you tried squeezing the hose from the SAD to see if it drops down again? Graham. Share this post Link to post Share on other sites

brianthemagical 1 Posted May 6, 2007 (edited) what do you class as a high idle? i had the same problem, can't remember what cured it though, it wasn't an air leak or anything like that, may have been ignition timing.
