Sounds like TPS, but check fuel pressure. Do the wiggle test on the harness.

Fuel pressure is 60 . It is a 05 so that's good? Would a broken reed cause this?

FP is good for an 05. Check your reeds while you're at it.

Wiggle test? Plug in Tps than wiggle while it is running?

Wiggle all parts of the harness while it's idling.

For what it's worth I just had the dealer tell me that the digital wrench only shows if the sensors are working not if they are within spec or operating range. Check TPS sweep with a analog meter. Check plugs? Fuel filter?

Mine was doing the same thing and it was the plugs. Cheap place to start looking.
