Hello,

My wife recently got stuck in a snowstorm. Some helpful people got her out and she drove a couple miles to work. After leaving work, her car started shaking at red lights (like big, slow shakes), but stopped as soon as she started to move or put the car in neutral. It did this on her way home from work and then continued when she left for a workout class about half an hour later. However, after this, it stopped completely.

Some people seemed to suggest engine mount problems to other people, which seems serious if it is that. However, since it did stop after a short time, is it possible there was snow stuck somewhere causing a problem and it finally just melted off? Or is the getting stuck in snow the same day probably just a coincidence?

Right now I'm planning to take it in sometime later this week most likely, but am wondering if I can avoid that since it hasn't exhibited any of the same symptoms for a few days.

Thanks.

 

It can be a dirty throttle body. If it went away for now I wouldn't worry till it comes back again. If it didn't throw any codes they might not even know where to start if you brought it in.

I cleaned mine and it didn't help. It intermittently got worse, then I replaced it and the problem was gone. But mine also got bad enough to surge at idle.

 

This is what my 2010 balt did for a while, now its blown up because it jumped time. What year/trim is the cobalt?

Edit: When she got stuck was she trying to power her way out first?
