This just started a while ago. I was heading up over a mountain pass abd kicked down to pass a semi. It pulled like a raped ape as usual, but when the rpm's hit about 2600 or so (75 mph area) all of a sudden it stopped pulling, tac stayed at 2600 but no power. I lifted the throttle and the tranny shifted back into overdrive, the rpm's dropped and once again I had throttle response. It was almost like I hit the rev limiter.
I tried it again, throttle down and pulled hard, rolling up speed but once again it just stopped pulling, only maintaining speed and tac stayed high until I lifted the throttle and it shifted again.
A mechanic buddy thought it was likely the IPR sensor, so today I replaced it. Took it for a drive and same thing, no change.
It doesnt do it as easy on flat pavement but more when more torque is needed, like up steep hills or under load.
