Hey guys! When I started my car up it got a notification about the drivetrain. My car went limp mode when the notification was active. I say active because when I turn off my car and back on it would go away and runs back like normal. In less than a week I noticed my car got a check engine light and on the highway when going from 5th to 6th, I noticed the car pausing for a moment. Yesterday I saw smoke coming out of my exhaust nit sure if it was grey or white but it wasn’t black or blue and it smelled like something not so nice for the nose. When I pressed the gass, more smoke came out of it. After a while the smoke dissapeared but the smell stayed.

Now the reason why I would lik to now the issue is that I want to try to fix it myself so I can finally have done something for my car. If you guys recommend me to bring it at a mechanic then I’ll just do that Just to be safe.
