Q: What would be causing my truck to have a hard time accelerating, jerking occasionally when pressing and releasing gas pedal?
The truck has a problem accelerating. Once it finally starts speeding up sometimes it will jerk when pushing on pedal as well as releasing pedal. When at a stand still it may die or remain running but always resists acceleration especially from a complete stop. We have noticed that shutting truck off and restarting it has helped it run a little better but only for a short time. What could be the cause of this? We have already put a hole in the catalyst converter and still no change. I had an idea that it might be the O2 sensor but not 100% positive. I also thought fuel filter as well but can't be absolutely sure on any of them being what's causing these issues. Please let me know something, anything will help. I prefer to be sure before spending a pretty penny on a part I didn't need to replace. Thanks!
