During braking, with no gas pedal pressure being applied, engine continued at high rpms making braking difficult. Vehicle with no gas pedal pressure would proceed at 30 mph in drive position of auto trans. Upon exiting roadway, when appling gas pedal while in park position, and releasing peddle, rpms were at 2200. Pedal was opperating freely and throttle cable/yoke was in fully returned position. I then continued looking for any obvious obstructions or seperated vacumn lines. Nothing appeared wrong. I then disconnected the mass air sensor causing the engine to stall. Upon reconnecting ams and restarting engine, idle returned to around 700 RPM's and no further problems occured for the remainder of my drive(approx 100mi more) no further diagnostics were performed yet. Vehicle is well maintained and has 65000 miles use.
