Rough Idle When Cold

5 posts in this topic

just picked up my 2003 focus zetec today.

the idle runs rough (jumps up and down) when the car starts from cold - i read elsewhere on here that this can be 'normal' in some cases but i've never heard of that before - surely not?

it settles down once the engine is warm or when the accelerator is blipped a few times.

any ideas?

any links to a how to guide for that, is that likely to be the problem then? where would i find the idle speed control valve - is it easy to access?

i also haven't any carb cleaner - would anything else work like wd40 or electrical contact cleaner?
