Title: Idle control valve
Post by: jayten1020 on 24 November 2016, 20:38:33: Evening,

I need to replace the ICV on my 3.0 omega, l know the original part is a Bosch , but l have seen aftermarket ones on ebay and motor factors, all ranging from £29-£150.

Should l stick with original or can l go for a OE product?

Cheers

Nope, the ICV cant respond that quick so would not cause rough idling, far more likely to be an air leak or ignition issue.

Agreed. I always start with the ignition for misfires or rough running. Listening for vacuum leaks while you do that is sensible, as that's the next system to examine.
