As I was browsing the different topics i came across a subject that mentions using the fast idle in order to use the air. Question is How do you engage fast idle on a 2007 FW Providence?
On my 06 Discovery, I use the cruse control. Set the rpm at 1000 or what ever rpm you wish, turn on the cruse and set the cruse just like you would on the road. To disengage, just tap the brake or turn the cruse off.
