Hi all
In an attempt to cure my stalling when cold, I've decided to spend some time this evening cleaning the ISV (Idle Speed control Valve) and the air flow sensor flap.
1st question. Which is the ISV.
2nd question - how easy is it ti remove the airflow meter assembly & clean? Any pitfalls I should be aware of?

Rob,
I believe it's fairly easy to clean aparently according to my mechanic it picks up carbon deposits.
When she went in for service earlier this week I called in to check progress and my car was sat idling very erratically. This was at 3pm and I picked the car up at 4.30pm with the problem solved and the ISV cleaned.
You'll be pleased to know it has completely cured my cold stalling issues.
