Jerking motion while stopped with engine running
I have a 2011 equinox and about a week ago while I was at a sop light, I started feeling a jerking motion in the car. I didn't really pay any mind to it but now it has gotten a little more noticeable when I am stopped and the check engine light has now come on. does anyone know what could be causing this and what can I do about it? I did put a small bottle of fuel injector cleaner in the gas tank to see if that would calm it down some but nothing.
