Okay I have noticed that the past couple of days that the idle has been real irregular and going crazy at stoplights and such. I ran the codes and found that the TPS sensor code came up(121) is the TPS sensor bad? Does this sound like a TPS failure to all you guys that have had it happen?

If you are getting the 121 code then the signal from your TPS is out of range and confusing the heck out of the EEC. It will definitely cause idle and driveability problems. It is a very inexpensive and simple replacement as long as you don't strip the heads of the Phillips screws. Get the Wells TPS215 at AutoZone for $18.99.

Picked it up yesterday, but still acting wierd on startup. It dies after a while when it is first started up and hesitates a bit while driving and also is down quite a bit on power. Cats? Just the running rich condition causing problems? Will a car running rich over time "clog" cats? I know I still need the DPFE sensor replaced, and I think the 332 code I get is from that, because I just cleaned the IAB area a few weeks ago. HMMM. :confused:
