The throttle in my truck is stuck wide open 90% of the time. Sometimes it will go to normal, but usually it's stuck. When I say stuck open I mean I can climb hills without pushing on it and going in reverse makes me nervous sometimes. (Between 15-35 mph). I ended up getting the TPS changed while I was at work on day. And of course just like I thought it wasn't that. I'm going to clean the throttle body today, but is there something I'm not considering? This is taking a toll on my brakes as well, but I'll worry about that later.

Good morning,

re right with your thought. I would start there and see if it continues.

If it does, then it is time for a throttle body.
