That's great - many thanks. I was hoping the butterfly wasn't shutting properly, so have already cleaned that out till its gleaming. This would not however, explain the achievable low revs when driving. Oddly, in desperation, I sprayed everything with WD40 - hoping some would seep in somewhere. After about 15 minutes idleing, while I screwed back the air filter box, and pondering, the idle speed dropped from about 1 3/4 to just 1/2-3/4. I'm wondering if 1) the long shot WD40 had an effect 2) the ECU reset I done a few miles/days ago had "learned" 3) it was just a case of warming up (but ive never known it to idle this high or for so long after a battery disconnect) Anyways - thanks for the tips, I think I'm sorted now (apart from the screwdriver bit now wedged behind a carb blanking plate !!!! And that, will just have to stay there! Cheers

IS 200 - Realise this is an old thread, but I have a high idle (1500+), but when driving (even foot off pedal) rev seem OK. I'm guessing the IAC motor is crudded up, so want to get a tooth brush in there with some carb cleaner (I'm guessing this is correct remedy). Three similar looking "things", I'm guessing 2 are throttle position sensors and the third the IAC motor. None of these are easily accessible (injector bar is in the way of one of the screws etc). Earlier post mentioned its the IAC is directly opposite throttle cable, so I think this answers the "which one" question, but how do you approach this access problem. Remove the throttle body? Will I need gaskets or anything? Remove the injector bar? Carbs are a bit of a new area for me, and haven't really messed around with cars in general for 25+ years, so would really appreciate any hints tips as a little bit reluctant/concerned/scared !!! Thanks folks

Thank you ColinBarber = that's brill

This is a first for me, but I'm going to have to change my steering fluid. I see the IS200 isDetron 2 or 3, but does anyone know how much I'll need for a complete change? thanks folks
