Hey guys so I have a question sometimes when I’m going low speeds in gear then I go to neutral the rpms go up to about 2k then go back down then it’ll do it again and was just wondering if this happens to anyone else btw it’s a 6 speed

Oh boy...
Yeah, I’ve had this similar happen. I have the 2013 Track with 6-spd. What you described was one of the symptoms I experienced. Eventually, I’d get stalling and limp mode with check-engine lights. It would always throw the same 3 codes: P2106, P2110, P0638.
I went though 3 iterations of Hyundai cleaning the throttle body, the codes coming back about 100 or so miles later with limp mode, and them replacing the throttle body. Each time they replaced the thottle body, the problem would go away for about 10k-15k miles.

You can check out my thread to what they actually did when they finally sent a Hyundai engineer to take a look:https://www.gencoupe.com/3-8-v6-discussion-2013-up/735988-never-ending-throttle-body-replacements-new-post.html
