sorry to bring up an old thread. This is a long shot, but did you fix your issue? I can't seem to find the solution anywhere? My truck has trouble going up hill past 60mph unless I downshift to 4th or even 3rd gear. I step on the gas and it becomes loud and not go anywhere.
Hey any chance you fixed your issue? I'm having the same exact problem. I have an exhaust leak on the driver side manifold, so I'm thinking the O2 sensor might be getting a bad reading. Not really sure though and I've just been chasing my tail for that last few weeks.
