cornish6544 Posted May 20, 2017 Share Posted May 20, 2017 So a few months ago i posted my problem about rough idle basically when the engine is to temperature the car will randomly rev itself up anywhere between 1000-2000rpm only for a second then drop back down or sometimes even to the point where it sounds like it could stall. At first it didn't bother me much but its getting annoying now nearly every time i stop at lights or in traffic it will do it. The car has had new coil packs and spark plugs less than a year ago fitted by a garage. I have just had the injectors cleaned and they came back flowing fully at 440cc and I've just fitted a new fuel filter still no luck. Anyone have any ideas?

savage bulldogs Posted May 21, 2017 Share Posted May 21, 2017 Have you checked the vac lines for leaks and cleaned the icv ? Sent from my SM-G930F using Tapatalk Quote Link to comment Share on other sites More sharing options...
cornish6544 Posted May 22, 2017 Author Share Posted May 22, 2017 Bulldogs- All the hoses seem fine I've had everything off recently doing some painting and cleaning and didn't see any disconnected or damaged. Ive only just seen the common ICV problem then when googled , Do you know of where i would find it on my car as I've tried google and its not much help. Mines a 1994 wrx Thanks Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted May 22, 2017 Share Posted May 22, 2017 The icv is on the right attached to the back of inlet with a light brown plastic top . If you do remove ,clean and refit it dont adjust the 2 screws on the top and buy a new gasket [emoji6] Quote Link to comment Share on other sites More sharing options...
