Sometimes Throttle Loping ceases when Auto shifted into Neutral (while driving along); sometimes requires engine to be Shut Down. One one [the worst] occasion, Engine wouldn't re-start when Drive engaged, unless throttle was revving up before pulling into Drive. Dangerous when Volvo_850 accelerating/Loping windy-downhill on brakes, and needing to turn off to kill Loping !!
