the check engine light has come on in my car, the truck bucks when i am driving on the highway only, but it only seems to do it around 3000 rpm.....as long as i dont rev that high i do not have the problem.....i have brought it to 2 mechanics and they tell me they dont know what it is. one guy told me he thought it could be a dead spot on my throttle position sensor.....any ideas??
