Focus 1.8 idle - Mordroc
Hi,
I have a 1.8 w plate Focus ghia which for the last few days has suffered from a rough idle at both cold and warm, though at cold it is a bit worse. It also feels a bit rough if you drive along in gear and take your foot of the accelerator letting it roll along.
The first morning when it started i had to pull over as the revs started climbing out of control. But when i re-started it it seemed ok.

THANKS IN ADVANCE :D

It sounds like the idle air control valve is dirty and sticking. I would begin by removing the valve, and giving it a good clean out.

OO i'd just like to add that as long as your foot is on the accelerator then it seems ok.
