Engine jerks & smells like burning oil

[JUSTBECAMEREAL]

Hey guys i have a 2012 1.8L chevy sonic lt (sedan) and ive been having troubles with my car lately. Whenever i start my car every so often my engine will jerk no matter if im im parked, drive or reverse, and it sounds different and louder when this happens. It also smells like burning oil daily. Would any of you be able to help me maybe figure out what could be the problem i would really appreciate it.

Engine mount maybe ?

Video of what it does would definitely help. Also a more accurate description. What do you mean jerk? Does it shake? Does it shudder? Does it vibrate? Does it clunk?

Several owners have talked about the burning oil smell on the forum and I notice it on my car as well.So far I have not seen a explanation for this.

Well i would say its like it bucks. The engine cranks does its think and a few seconds later bucks and then 5-10 seconds after that it will do it again

Like it's going to stall? If so .. Maybe something with the fuel pump or fuel injectors? I'd change the spark plugs and put a bottle of techron in fuel.

Bum PCV valve?
Remove plastic cover over spark plugs.
Place thumb over vent on PCV valve (round gizmo as big around as a quart jar lid upper rightside). If the idle changes, you've got a bad valve.

Its an old 1.8L, I'm surprised no one has mentioned the torn intake tube issue yet.

any engine lights for running lean?

Edit: just saw the dates here, I'm betting he got it solved one way or another...
