garrygt Posted June 15, 2015 Share Posted June 15, 2015 My car idles lumpy, the revs go up and down by themselves, brand new icv on it, its also takes a few seconds to start sometimes. Im thinking it could be something to do with the wax stat in the throttle body but wanted to see if anyone else had any ideas before i take it apart. Quote Link to post Share on other sites

garrygt Posted June 16, 2015 Author Share Posted June 16, 2015 It doesnt do it all the time, sometimes it will sit on 1k rpm just fine. I think the timing is fine mate haha. Quote Link to post Share on other sites
Calum122 Posted June 16, 2015 Share Posted June 16, 2015 My brother had this and it was vac leak. His idles spot on now. Also make sure there isn't any electrical load on the engine. Quote Link to post Share on other sites
