Question about Hyundai Motor 2002 Elantra
Not sure what your background is, but I just posted a question.
-high idle on startup sometimes
-harsh shifts between 2-3 when cold
-only once did it not shift up from 2nd
-when on highway and driving for a while, engine surge (like overdrive kicks on and off)
-when engine is hot and driving in rush hour, tranny doesn't shift very smoothly
Before spending the money on a new TPS, you could use electrical contact cleaner on the connector and harness, and see whether that helps. It could be dirty/corroded terminals on the harness causing the problem. It's cheap and easy and worth a shot before laying out the cash for a new TPS.

Yes, I had the P0121 code TPS Range/performance A code come up. Sound like a TPS switch replacement?

Well i saw your other post. try changing the TPS and see if that corrects it because that will screw up alot of stuff for your tranny.

If you are getting a range performance code, then you need to put the car in nuetral and adjust the cable on the range switch on the transmission. If you look almost under the air filter you will see the range switch and the cable being connected to it. If you notice, there are two "prongs", one on the cable bracket, the other on the range switch. Each "prong" has a hole in the end of it and they must be in alignment when the gear selector is in nuetral. Put the car into nuetral and then use a 12mm socket to loosen the nut on top of the cable bracket and adjust the two holes until you can slide a pin into them and lock them back down into place. This should stop your problem.
