2000 SL2
Default Weird high rev at idle?

The other day during regular driving my 00' SL2 all of a sudden started to keep RPM at about 1300-1500 constant, even at idle.

This was totally random and kept persisting for a few miles and it finally went back to normal after I shut off the car and started it again.

It didn't come back YET, but I'm sure it's something that will get worse with time.

Has anyone experienced this before? I saw another thread about high idle and it the TPS was mentioned. Should I go to that part first if the issue comes back and persists?

REWARD EXCELLENCE!

So I bought this TPS from an Ebay reputible seller, and the packaging says GM OEM as well as Made in Japan. Is this real? I find it funny that GM would be making parts in Japan, actually quite ironic. Pics attached to post
