My Brother Focus, Any ideas.
My brothers 1.6 focus has just started developing a bit of a weird issue.
As a whole the car runs absolutly perfect. However on pulling up at traffic lights its begun to start hunting, ie the revs go up and down a few hundred RPM, then drop, then raise again.
Dont really know what to suggest for him, its got all new plugs/filters and stuff. Any ideas what this maybe is.

So my brothers done the plugs, the Idle control valve and still doing it.
Asked him to leave the ecu disconnected for a few hours but its still doing it.
Any other ideas guys?

ive seen a few mk1 focus's suffer from vehicle speed sensor (vss) problems, this can cause it to hunt when pulling up at junctions and even cut out, has he noticed the speedo drops to zero when he is driving at all? as this can also be vss related.

It was a new Idle speed valve.
RS20004X4. Very interesting. He had issue with the speed sensor a couple of months back. However it just stopped playing up....

Mine does this, does it worse / moreso when more electrical things are on, sometimes stalls.
I cant use the lights wipers and my headunit at the same time or the car will stall

could be pcv. this is also known to cause issues especially with soft or split pcv pipes. meant to vent some pressure to atmosphere to prevent stalling and is known to cause erratic idle if pipes are split or collapsing
