well its at the dealership and they said the downstream one is a little shot something about the heat sensor on it or something. they said it wouldnt really make the car run this rich.

nope had the dealership check all the sensors, the only one that was crapped out was the TPS got new one thought it would solve problem but didnt. the dealership and myself are really confused on this one!

You will generally not get a code for CLT failure. I highly doubt the flat-rate technician at the local dealership removed every sensor in the car and tested it individually. He hooked up the scanner, got no codes, and then said the sensors were good.
When the CLT fails, it doesn't stop working altogether. It just tells the ECU the temperature is way below zero. Now, you can take the car back in, wait for the technician to have the time, pay the high per-hour rate, and ask him to check the temperature being reported by the CLT. OR, you could go to Autozone, spend less than $50, and get both the sensor the ECU reads and the one for your gauge in the dash (meaning you won't be confused if you got the right one, since there are two installed at the same location) and likely solve this problem tonight.
They are located below the radiator cap. Be careful removing them so you don't break off the connectors. If you've got corrosion around the area, it's a good sign that you're on the right track by replacing them.
While you're at Autozone, pick up a Chiltons manual for your car as well. Tells you how to test some sensors yourself to save some cash.
When you fix this, pay a friendly visit to the shop and tell the technician what you found. Be cool about it and just tell him you thought he'd want to know, since it was such a puzzle to you both. In the future, he can spot the problem right away and you bank some karma in the process.
Good luck.
EDIT: Come to think about it some more, spark plug wires tend to cause a lot of hesitating in these cars. A new set at Autozone is like $45 and comes with a lifetime warranty for free replacement. How old are your plugs? Are they gapped correctly?
