Rpm bounces while moving

Watch the TPS voltage fluctuations. It will show a voltage spike or drop better than watching the TPS count.

A side note. If you're getting voltage fluctuations on an evenly held throttle pedal, its not always the sensor. So don't just throw one at it right away. Could end up being a waste of $$. A lot of times its chaffed wires somewhere under the hood. Often times under the loom clamps around the back of the engine. They are a 5 volt circuit and are much more of a delicate circuit than a standard 12v. There are 3 wire twisted to each other. Signal+ signal- and 5 volt feed.
