Also guys...You're forgetting it might be an air leak somewhere before the throttlebody, before the air intake. :gap:

My 7 had a leak in it's throttle body, and it was causing the revs to modulate...up and down, up and down. That was the problem, though.

Take some carb-cleaner and spray around the area, if your car revs up, then you know you've got an air leak.

Be careful though... :chuckles:
