Engine idleing at 2500rpm when it gets cold.

[haGGard]

Hi,

Tonight, and the other day when the temperatures got really cold and icy, i have found the my car seems to be driving itself! At first i thought it was the auto-choke not turning off, but even when ive been driving for a while and the car had properly warmed up its still trying to idle at 2500 RPM!

Found it quite dangerous, especially on the icy roads! It also meant i had litterally no engine braking! Apart from that i looked pretty daft sitting at the traffic lights with my engine racing away lol.

Only really lasted about 5-10 minutes though and then it seems to go away and drive normally.

Any ideas?

Try cleaning your idle control valve plenty of threads about on how to do it.

Have you over adjusted your throttle cable? if so, loosen the cable a lil bit

I have never touched the throttle cable, its only ever done this when the air temperature gets very cold, say past minus 5. I'll give the ICV a look at tomorrow when i have some free time.

i had a problem with my idle a while back took apart the throttle body and replaced the small gasket and it solved it
