jack 0 Posted April 24, 2008 hi folks, when i start my car for the first time in the day it has an uneven idle, the revs go up just over 1000 and back down, they continue to do this for about a minute and then everything is fine, any ideas of what is causing this.

til2143 0 Posted April 24, 2008 Sounds like the idle control valve needs cleaning Quote Share this post Link to post Share on other sites
CazzaVR 0 Posted April 24, 2008 On cold start, the idle should be up around 1000, but should be even. It will then drop slowly to around 650rpm. As said, give the ISV a good clean and check for airleaks in the intake pipework. Quote Share this post Link to post Share on other sites
