2015 Elantra runs awesome but the idle is terrible. I have cleaned out the throttle body but it does not seem to help. No vacuum leaks I can detect either. Very shaky idle when in gear, not in gear, A/C on, A/C off. Help!

Hello, is the idle actually rough, or the way it feels in the vehicle? Could you have motor mount issues not properly dampening the engine? Ignition and fuel delivery, air intake and exhaust flow, along with properly functioning emissions components is essential. As is engine timing and compression. Testing has to happen, if mounts aren't an issue.

Mounts are good. Car has 64,000 on it, original owner and I have done all of the maintenance. This is definitely an engine issue. No codes to go on though. I will need to bring it in to a shop to have it scoped I guess. Thank you.
