I would not think its a Throttle position sensor either,,trans gets input from the TPS,if that was the problem you would also notice hard/firm trans shifts..
Boatnt... It does have some different shifting points when it is acting up. It seems to shift out of the gears faster, I will be in overdrive by 35mph. Some times it will not shift into 3rd until 3000 kinda erratic.

Thanks all for the suggestions |
Check the coolant temp with you dongle to see if it is accurate. Put a fuel pressure tester on it to verify fuel pressure.

Quick update:
The last few days the truck has been running pretty good, slight hesitation above 60% throttle. I disconnected the mass air, put in a known good mass air and TPS with no change. This weekend I will hook up a fuel pressure gauge and do a back pressure test on the cats. I hooked it up to my brothers Snap on Solus and it had no stored codes and all checked good. As always, thanks |
Another update:
Fuel pressure checked out good. There was a small measurable amount of back pressure on the passenger side cat. I replaced the TPS. Today I replaced the battery and now all hesitation has gone away. I can put it to the floor and it runs great. Thanks everyone for all the suggestions. I hope this was it. |
Rookie: Sometimes all it takes is a battery. These vehicles are sensitive to that and it seems strange that a battery will "function" but not allow a vehicle to run right.
