High engine idle on start up

[Alexl8891 Lurker Find all posts View Profile Close Alexl8891]

Just wondering if anyone would have any idea why my car would be idling high on cold start up? (diesel)

First time it has ever happened. Was revving at approx 2000, it sounded like someone was depressing the accelerator pedal on start up.
Just got a 90000km service last week, also had a primary fuel filter installed as well during service. Other than that it's all standard

Is there anything I could do or have a look at or clean up before I take it to a mechanic?

Thanks.

D4D or V6? Is the idle up switch on? If so the engine will fast idle on cold until operating temperature.

Sounds like Rusty suggested. The fast idle switch. Located near right knee.

Thanks for the help.

I think you guys might be right. That area is where I placed my spotlight switches and I was fumbling around last night trying to turn them on, may have hit that by accident. Will check it out asap.
