Amjad Posted May 19, 2010 Share Posted May 19, 2010 Hey guys,As above really, my idle is sitting at 1100rpm when warm and I just want to wind it down. Anyone know how to do this? Pics of what to adjust etc?ThanksAmjad Quote Link to post Share on other sites
Steve GT Posted May 19, 2010 Share Posted May 19, 2010 look at your inlet manifold right near the throttle body at the back theres a hole with a screw down in itturn that and it will increase/decrease your idle. keep turning it the right way until the idlings at what you want800-1000rpms the best to set it at Quote Link to post Share on other sites
Amjad Posted May 19, 2010 Author Share Posted May 19, 2010 I can't find it, have you a pic by any chance?There one teeeny little bolt on a threaded rod underneath the throttle spring where the yellow bush is, is that it? Quote Link to post Share on other sites
enots Posted May 19, 2010 Share Posted May 19, 2010 dunno if its the same with n/a but my idle screw has got a rubber grommet covering the hole on top of the inlet Quote Link to post Share on other sites

nastyrash 2003 Posted May 19, 2010 Share Posted May 19, 2010 no fella your throttle body does not have it, check for any inlet leaks on all vac pipes, the 1 to the fuel presure reg is normaly the fav. Quote Link to post Share on other sites
Amjad Posted May 19, 2010 Author Share Posted May 19, 2010 Thanks for the help guys, a little bit of tweaking and twisting of the TPS sorted it out in the end! Big thanks to Asad! Quote Link to post Share on other sites

(NAS) starlet ep82 Posted December 29, 2010 Share Posted December 29, 2010 Whats a TPS?Think he means ''throttle position sensor'' (TPS) Quote Link to post Share on other sites
Asad Posted December 29, 2010 Share Posted December 29, 2010 this ^Just to add, to adjust the idle on the N/A its a little different they dont have the said "screw".......the only way we can adjust it is via a small allen screw at the throttle cable end on the throttle body. this is factory set and has some sort of yellow liquid seal on so should never need messing with......meaning if the car does have idle issues try and sort them and use this only as a last resort.....throttle body gasket can cause idle issuesclean the ICVReset the TPS (calibrate it) this was the issue with amjadclean all the earths + add a few moreservice itthe list is endless but if you done that much and still cant idle post up lol Quote Link to post Share on other sites
enzo_e492901 Posted December 30, 2010 Share Posted December 30, 2010 I do not know for sure but I believe the idle on N/A's is controlled by the plate circled in red in the photo below. It seems to interact with the idle control valves shaft via a spring and a kind of insert. The insert seems to control the rotational stop points of the shaft and therefore the maximum valve opening. If you loosen the screws the plate will rotate a small amount, it is sealed with silicone so you would need to take it to bits, clean and apply new silicone, put in back togeather loosely and while the silicone is wet adjust the plate with engine running and tighten up the screws when you have it adjusted correctly. This adjustment may not be anything to do with idle adjustment, it may be to do with valve function, I'm not sure!I believe the screw Asad_EP5DR talks of is the butterfly stop screw, used to stop the butterfly wedging it's self closed against the wall of the throttle body bore. It should be adjusted so that the butterfly is totally closed and dose not get jammed. If this screw is used to adjust idle it alters the angle of the butterfly shaft and therefore possibly the position (or signal) of the throttle position sensor.Like Asad_EP5DR said above idle should not need adjusting on our cars. If your idle suddenly changes look for the cause before you adjust.gavin Quote Link to post Share on other sites
SRTom Posted December 31, 2010 Share Posted December 31, 2010 I gave the dizzy a twist and that droped the idle, im just waiting for it to cool down so i can see what it starts like from cold. Quote Link to post Share on other sites
shorty Posted December 31, 2010 Share Posted December 31, 2010 ^^not the best way totakle idle problems bud, you are altering the timing by twisting the dizzy, so it will make the idle rise or fall depending on wich way you twist but thats not the solution as you will affect the econemy and the power of the engine.
