My 2000 SVTC is having problems dropping rpm's with clutch engaged. It has happened before, but went away. It has come back and bugs the hell out of me. When I push the clutch in, the engine rev's a little higher then drops back to what it was when I engaged the clutch. After 4-6 seconds with the clutch still pushed in it will drop rpm's. Please help. :shrug: :shrug:
