Title: Cold Start Revving
Post by: tokyo_black on December 11, 2006, 12:27:53 PM
Hi guys.

I am having a strange cold starting issue.

It only ever happens on the first start of the day, and what happens is I start up and it turns over fine.

But if i then move the car the second i press the gas pedal the idle point sits at those revs. So say i pull out of my street after starting up and i get to 3k then change gear, the revs will constantly be at 3k. Regardless if im touching the gas at all.

It\'s like the cable gets stuck down or something and its v.dodgy. Even if i push in the clutch the revs keep revving at the highest point i reached.

This lasts about 3 minutes until the engine is a little warmer and then stops. Same distance/time every morning.

Anyone have a clue whats happening? It never did this in the summer.

ummmmm ive had this problem a while back and a mate fiddled round with it a bit then it was fine, theres a screw in the enigne bay for adjusting the idle, i think the cable does sometimes get a bit stuck and may need a bit od tweeking.  Will see if i can find a diagram of where the screw is. :Typing

If it\'s a problem that goes away once warm it sounds like it could be to do with the double throttle linkage...if you haven\'t had it removed :3Confused

Update:

Fixed this problem. Turned out to be a sticky accelerator cable as suspected! :)
