When i start my car from cold it revs its self up and down, sometimes as high as 3000 rpm. Then when its warm its fine. It never used to do this.

 

Does any one know what could cause this??? :confused:

mine does this especially if i havent drove her for a few days once warm fine

 

also if im at the lights the revs will pick up a bit strange more than likely cold weather doesent help :(

Fuel surging!????

think they call this 'hunting'?

Go cleaning up of things.

New fuel filter, clean throttle bodies, clean connections, check for air leaks. That usualy gets rid of it.

I would say vacuum leak and maybe TPS.

 

Greg- if your idle is high at some lights, but not others, then check your TPS. I had the smae problem, but once I changed the TPS it was all sorted

iv cleaned every conection cleaned t bodies changed fuel filter etc odd not a big problem

I had same problem - and one/two of the pipes coming off the induction were split - i replaced them and all was well in the land of Z again
