Chrishoughton1989 Posted August 28, 2013 Share Posted August 28, 2013 Help please. I have high idle and I tried unplugging the icv when running and it made no change. Is this normal ? Thanks. Quote Link to post Share on other sites
Adamep91 Posted August 28, 2013 Share Posted August 28, 2013 check around inlet mani for air leaks and all your boost pipes for leaks mine was reving high after I put my engine in that sorted it Quote Link to post Share on other sites
Chrishoughton1989 Posted August 28, 2013 Author Share Posted August 28, 2013 Will do. Should disconnecting icv change it ? Thanks. Quote Link to post Share on other sites
Adamep91 Posted August 28, 2013 Share Posted August 28, 2013 I don't think so make its probly just a air leak from somewhere mate Quote Link to post Share on other sites
Chrishoughton1989 Posted August 28, 2013 Author Share Posted August 28, 2013 I will try spraying inlet with something to find the leak. I though the revs should drop if disconnect icv ? Quote Link to post Share on other sites

daniel_g Posted August 28, 2013 Share Posted August 28, 2013 Pretty sure almost every starlet has idle issues, when its hunting ie, up and down up and down, thats a vac leak. Well on these cars anyway. Constant high idle wont be. The idle on my GT jumped about a bit from time to time, would sit at 1k for ages then suddenly go to 1.5k, i blamed cold weather haha. From experience the ICV at the O/S of the inlet does sweet fuck all anyway. Quote Link to post Share on other sites
Chrishoughton1989 Posted August 29, 2013 Author Share Posted August 29, 2013 Mine hunts perhaps once or twice then sits there at around 1500 ish. But I'd I turn the steering it rises to 2000 and sits there for a while. Quote Link to post Share on other sites
daniel_g Posted August 29, 2013 Share Posted August 29, 2013 Thats why the steering rack has vac lines, to raise the idle when the engine is under load from the PAS. Quote Link to post Share on other sites
Chrishoughton1989 Posted August 29, 2013 Author Share Posted August 29, 2013 Ok cheers. I soaked the inlet etc with wd40 no change. So I turned the idle screw all the way in and it ticks over at 1100 ish. Is that normal? Quote Link to post Share on other sites
Chrishoughton1989 Posted August 29, 2013 Author Share Posted August 29, 2013 It gets stranger. I switched it off after a drive then back on now it's 900 ish lol Quote Link to post Share on other sites
JayJ Posted September 13, 2013 Share Posted September 13, 2013 Bump for this problem as my car does exactly the same. I haven't found a single leak and my idle screw is completely turned in. Stock ecu:On cold start it idles around 1500 and quite fast drops down to 1100 and stays there. If I drive the car so it's warmed up and then stop, it will idle 1100.If the engine is running warm and I turn it off and start again it will idle around 850-900. Hit the gas pedal and it will idle 1100 again. JAM ecu:Idle never goes below 1100. The real problem is that MOT emission test requires idle to be below 1000. If I tell them to switch the car off and back on before emission test I don't think it's legit enough. Quote Link to post Share on other sites
mikey4410 Posted September 13, 2013 Share Posted September 13, 2013 Mine idles at 500 rpm .lovely and low and great engine braking. Quote Link to post Share on other sites
