Hi, my car is idling at 1800 when cold, and only drops to 1250 when hot, i was advised to block the egr valve but it made no difference. i can't find any vac leak, i am wondering could it be the idle valve but i don't know where this is located. any help greatly appreciated.

Suggested Solution

Many Vauxhalls need the idler reset after a battery is changed or run flat.
But you do need Vaux software to do this.
