Could be either of those things. But when my TPS failed it did what you are describing it had one certain RPM that is would buck violently then if I gave it more or less gas it smoothed right out. Best thing is to pull the codes if it is the TPS is should show up that is how I found mine.

well if it's a 5spd mine used to do the same thing, i replaced every single sensor know to man on it and it still does it. it just didn't like low RPM with the clutch out.
or stick a VOM on the signal and ground wires of the TPS and see what you are reading at throttle 'tip in'. look for a clean sweep with no breaks or dead spots.
is the idle set up per spec (did you run through the setting procedure?).
good luck.

someone seeing it first hand in a shop would likely know better than us. if you read what i posted above, you can check the TPS firsthand, and if it tests poorly, you can feel good about getting a new one.Matts89LX5.0 said:idles nicely at 750 rpms. when i was getting it inspected at a friends shop, he said looks like i need a new tps based on the miss on the dyno running. Just figured i would run it by you guys since i'm an electrical/sensor idiot.
good luck.
what codes are you getting? i would pay close attention to any EGR/EVR codes (EGR might be opening when it shouldnt).
thing is, i dont see how forum advice can compare to someone with the car in hand, with it on a dyno.
good luck.
