welshbuddy Posted May 13, 2012 Share Posted May 13, 2012 Hey guys, cars had a problem last 2 days, it tries to stall as I'm coming to a stop. I got to keep reviving at traffic lights to keep UT from stalling . I've done a search but there was no real awnswer. When I start the car it does have Abit of a erratic idle. Any ideas. Cheers.

Ian C Posted May 13, 2012 Share Posted May 13, 2012 This is usually caused by overfuelling or a stuck idle control valve. Check your oxygen sensor via the diagnostics port and clean up the ICV Quote Link to comment Share on other sites More sharing options...

welshbuddy Posted May 26, 2012 Author Share Posted May 26, 2012 + did you just blast the Carb cleaner through a few times? then refit?? Quote Link to comment Share on other sites More sharing options...
SPG Posted May 26, 2012 Share Posted May 26, 2012 I removed the ICV and left it to soak in the Carb cleaner over night buddy, i think gave it a good rub down with a clean dry cloth and sprayed a little more cleaner on it and fired it back in. I cant say that i remember there being any water in the pipes though buddy, hmmmmm may have to go and remove it from my project sup to confirm.
