reduced engine power & check engine light comes on. speed will reduce to about 25 mph on level ground. I have spent about $1500 so far on this with no fix. fixes have been broken wires, throttle sensor, throttle housing, air filter, gas cap, the last fix was replace throttle body and now am told it was bad and now am told they don't make the part any more. this problem occurs some times once a month some times once a mile. it will cure it self by turning off engine and restarting a few times.
