Engine Performance problem
2001 Volvo XC70 All Wheel Drive Automatic 144000 miles
My engine rpms surge and wane to nearly a stall when idling. The rpms range from about 500 to 1200. When the rpms drop to 500, the engine acts as if it wants to stall, then the rpms increase to about 1100 to 1200. What could be causing this.
