Whitenoize Posted August 19, 2015 Author Share Posted August 19, 2015 Bump anyone ???? Quote Link to post Share on other sites
Broony Posted August 19, 2015 Share Posted August 19, 2015 tbh the mot man is a bit anal if hes picked you up on idle speed but if it has failed emission that's what it could mean by idle speed Quote Link to post Share on other sites
Whitenoize Posted August 19, 2015 Author Share Posted August 19, 2015 Yeah that's what I thought but I've put the cat back on so hopefully that cures it... Also any idea wet the fuse is for the rear side/brake lights think I've just blew it fs Quote Link to post Share on other sites
Broony Posted August 19, 2015 Share Posted August 19, 2015 lights are normally 5amp? check fuses under the dash Quote Link to post Share on other sites
Whitenoize Posted August 19, 2015 Author Share Posted August 19, 2015 Is there a way to bring the engine idle speed down I went and got the car to do the work on it and it's constantly sitting at 1500rpm Quote Link to post Share on other sites

JamesP Posted August 19, 2015 Share Posted August 19, 2015 Could be a vac leak causing the bad idle. I've had a lot of trouble with a mates car I've been working on idling really badly due to all the vac lines being a mess. Would be worth checking them all as it would be an easy fix.

Broony Posted August 19, 2015 Share Posted August 19, 2015 you can adjust the idle screw on the inlet, might need to clean the icv Quote Link to post Share on other sites
Whitenoize Posted August 19, 2015 Author Share Posted August 19, 2015 If it was down to vac lines would the idle not be all over the place? it's like it's a cold start all the time and the rpm isn't adjusting when the engine gets warm going to try cleaning out the icv tomorrow see if that helps Quote Link to post Share on other sites
Socks Posted August 19, 2015 Share Posted August 19, 2015 There is an idle adjustment screw on the throttle body? Quote Link to post Share on other sites
Whitenoize Posted August 19, 2015 Author Share Posted August 19, 2015 Is there? I had a look and couldn't see any screw Quote Link to post Share on other sites
Socks Posted August 19, 2015 Share Posted August 19, 2015 May need to take a black rubber bung out. Quote Link to post Share on other sites
aaddzz123 Posted August 19, 2015 Share Posted August 19, 2015 Remove the rubber bung on the top of the body. Be a flat blade screw which adjusts the idle... Before you do that though, with the car running put your hand over the throttle body. If it continues to run then you have a vac leak which is going to be what's causing the high idle. If it cuts out then just adjust the screw. Quote Link to post Share on other sites
Whitenoize Posted August 19, 2015 Author Share Posted August 19, 2015 Awesome thanks a lot was out in the pissing rain looking for a screw but yeah will do that tomorrow and hopefully it sorts it out..failed mot today because of it id never even noticed it it's only a about 300rpm out think the guy is being a knob tbh Quote Link to post Share on other sites
Whitenoize Posted August 19, 2015 Author Share Posted August 19, 2015 (edited) Another stupid question while I'm in a tool wer is the fuse for the rear lights I can't find it anywhere lol ever mind it's me being a Mong exactly same place as a gt lol Edited August 19, 2015 by Whitenoize Quote Link to post Share on other sites
StuDoc 72 Posted August 20, 2015 Share Posted August 20, 2015 If its constantly idling at 1500 thats almost double idle speed. Sound like a stick on theres a loose/missing/split vac pipe. Quote Link to post Share on other sites
Whitenoize Posted August 20, 2015 Author Share Posted August 20, 2015 What should it idle at? I brought it down to 1000rpm using the screw on the tb Quote Link to post Share on other sites
Whitenoize Posted August 20, 2015 Author Share Posted August 20, 2015 If its constantly idling at 1500 thats almost double idle speed. Sound like a stick on theres a loose/missing/split vac pipe. had it running and covered the tb and the engine stopped so I assume there isn't a leak ? Quote Link to post Share on other sites
StuDoc 72 Posted August 20, 2015 Share Posted August 20, 2015 Warm Idle on most cars is about 800rpm. Cold will be about 1200. If it didn't kill the engine though I suppose that means there isnt one. Quote Link to post Share on other sites

Ollieh17 Posted August 20, 2015 Share Posted August 20, 2015 Only time my glanza ever idled properly was when i took out the ICV, blocked up the wax stat valve and looped all the coolant lines Quote Link to post Share on other sites
