Hi I just got my 08 Turbocharged cobalt and it idles at like 700rpms and when I move up into 900's the steering wheel starts to shake but when I get out of that range it goes back to normal. Is this normal like its just the torque pulling or somthing I should go take a look at?
Your Loving Noob,

Check and see if it has poly motor/trans mounts.
