mc92 Posted September 9, 2019 Author Share Posted September 9, 2019 Idle is sometimes high. Bonking on the IACV with the handle of a screwdriver takes the idle back down to normal so I've assumed it's sticking in some way. I've taken it to bits and cleaned it and it's better than it was but not perfect. Sometimes the idle is too low as well which is probably something else but I feel like the IACV is a good place to start. Any other suggestions I'm all ears Link to comment Share on other sites More sharing options...

Are you auto? If you are and are getting funny gear changes...could be the ecu like many na auto owners are getting recently? I personally am getting tired of supra ownership lol Link to comment Share on other sites More sharing options...
mc92 Posted September 9, 2019 Author Share Posted September 9, 2019 Mine's a manual. The butterfly seems OK to me, I was playing with it yesterday morning since I had the intake piping off to clean my O2 sensors. I'm half suspecting the ECU for another issue mine's having*, which is a singular intermittent complete power cut when starting a journey, but haven't got around to taking that out yet. I'll have a peep at the state of the capacitors at the weekend if it's not raining. *as described here: http://www.mkivsupra.net/vbb/showthread.php?353578-Intermittent-power-cutting-on-NA Link to comment Share on other sites More sharing options...
mc92 Posted September 13, 2019 Author Share Posted September 13, 2019 Bought a chinese knockoff one from Ebay for the moment, worth a punt for £33. Thread closed for now. Link to comment Share on other sites More sharing options...
