mlcarlson56 Well bad news, it started doing the same wierd rev thing when I shift. For now it is just holding where it was but I am assuming it will get worse again. I did find another post on the forum that may be of help. Just figured I would share it because I just found it and started to read through it. Hope it can help us both!

mlcarlson56 I actually took it to one of my buddies who owns a shop to see if he could help. We did some more digging around and testing. Turned out that the TPS was going bad and that was causing the revving issue. We replaced that and now it seems to be driving fine. He did make sure to mention that this sensor can go bad if the throttle body itself is starting to go bad so I am going to keep an eye on that in the future.

The part was fairly inexpensive so I hope this helps you.

The weird thing about it is that when the car slows to a stop, below 5mph, the engine will return to normal idle rpm. Above 5mph though anytime the clutch is in or I am out of gear the engine revs to around 5,000. Obviously I would like to be able to look at the engine while driving but having my hood open and going +5mph might be a safety hazard... The other thing I was thinking is that my cruise control could be acting up as this is the only other thing that can act on the throttle body to rev the engine, however i made sure that it was switched off while I was having this issue.

I will keep looking into it and if I figure out anything, I'll be sure to pass it on. If anyone has some suggestions I would like to get this fixed as well without taking it to a shop and paying for it.
i am having almost the same exact symptoms, it seems like it has acted up in the cold weather. my throttle body was sticking and i cleaned it and it solved those symptoms but not the reving symptoms. so i know its not a throttle body problem. thanks man, ive heard that a tune could do wonders including clear this up
