Hi all- I'm looking for some advice please guys. I've recently bought a diesel Focus Ghia (2000 reg).
When the engine is cool, the idle speed is around 800rpm- about right I reckon. When the car warms up, however, the idle speed is around 1500rpm.
The car has been regularly serviced by Ford and has covered 103000 miles.
Can the idle speed be manually adjusted or do I need to get it professionally looked at?
Aside from the idle problem, the Focus seems to run perfectly with no missfiring or farting!
Would really appreciate your thoughts on the subject- thanks in advance.....-Simon

the idle speed is controlled by the ecu so no manual adjustment is possible, it sounds like a sensor problem but which one is a guess. you need to get a scan done to see if any codes are stored most likely a temp or maf sensor.
