This is just a heads up for those who have the earlier XD's...
For years now the guys on RDTiburon.com have known that the older model TPS', which are the ones branded with "Dae Sung", are poop. Well, yesterday I realized I had that on my car. Let me explain...
First start since engine swap was yesterday (for those who don't know my engine blew back in december and I just had little time to work on it). Everything was chill until I moved the car (was idling perfect). Then the idle went erratic. We realized that when you poked the TPS from outside (lol), the idle would change dramatically. I checked on RDT and that was the main symptom of a shot Dae Sung TPS.
I might add that a big difference between the Dae Sung (bad) and the Kefico (good), is that the Dae Sung is spring loaded. Another difference: I always noticed that my buddies had 7+% of throttle on idle (measured with my scan tool), but I always had 3-4%.
Anyhow, I got lucky. The TPS on my car was the Dae Sung one, but the engine that came from the junkyard had the Kefico one on the TB! Woot! Problem solved and now the car works like a charm :)
I just felt like throwing this out there for you guys because when I ran a search there weren't a lot of concrete results on the forum, so this might help someone in the future.
For reference, my built date is 11/01. I don't know exactly when Hyundai made the switch from Dae Sung to Kefico, but apparently it affects "early models", but I am not aware about what is considered ''early''. Perhaps someone can shed some light on that.
Here's a pic I took of the two sensors just so you can see the difference:
