Never had to deal with the TPS so I am wondering what some of the symptoms are when they are going out.

I have been having problems as of late with the throtle being very touchy when going over normal slightly bumpy roads. This is not normal for my truck and it only happens on occasion. The RPMs at idle will run up to about 900 and the engine sounds like I have a lope tune going if I am in gear and driving. I can get it to stop on occasion by reving the engine. If not, I can kill the engine and let it sit for a minute the problem goes away. The truck will run flawlessly all day then BAM! Here we go again...
Been fighting it for about two weeks.
The chip is taped in really well and the contacts are clean.

Thanks for the help!

When my TPS was going out, it would intermittently go dead while going down the road. At first I thought it was the cam position sensor, but the tach would not go crazy.
