Hey all
New I owner of 2001 xc turbo all wheel drive. Nice car but recently started reving to 4000rpm when we start it. every time.
I did pull a p0455 code about a day or two before this started because the engine light came on. Not sure if they are related or not
any ideas?
thanks
Greg

 

You either have a HUGE vacuum leak or your throttle body is done for.

 

Any way to isolate which?
it's tough to find a vacuum leak when it only happens at startup.
thanks for the help

 

Vacuum leak would be present at all time, not just startup.
