sosolid Posted October 5, 2013 Share Posted October 5, 2013 when the idlling is not right what could cause this. when waiting in traffic the idling goes up and down from .5 to 1000rpm and so on. could the idle control valve have gone? Quote Link to post Share on other sites

Danza V Posted October 5, 2013 Share Posted October 5, 2013 Common issue.. You can block it off completely, and if the idle issue continues, it's not your iacv. I'd then be looking at vac leaks etc Quote Link to post Share on other sites
sosolid Posted October 6, 2013 Author Share Posted October 6, 2013 could it be a misfire? ht leads distributor etc. it does this when has been driven and when i stop in traffic or park up. it goes up and down. Quote Link to post Share on other sites
JayJ Posted October 7, 2013 Share Posted October 7, 2013 If your idle control valve is broken, you will get a stable high idle between 1000-1200, because the valve is leaking all the time. Quote Link to post Share on other sites
sosolid Posted October 7, 2013 Author Share Posted October 7, 2013 well. this is what happens. when i start the car works perfectly. when its warmed up and im driving then stop at the lights or pul up to park the revs drop to 1000rpm then lower like the cars gonna die then up to 1000rpm then down and it does this for about 30 seconds and then stop at about .800rpm and works fine. what can cause this??? ie got a video on my phone but don't know how upload it on here.

sosolid Posted October 7, 2013 Author Share Posted October 7, 2013 i heard that if you try to clean it the gold metal bit inside can break? aint it easier just to change it ? Quote Link to post Share on other sites
JayJ Posted October 7, 2013 Share Posted October 7, 2013 I just bought a new valve from Toyota last week and it cost 202 euros, so if the price is not a problem go ahead :-)You can try to clean it without opening it, just spray cleaner inside so all the dirt comes out and then shake it dry.
