hey guys, just noticed the other day that my car shakes when starting it up for about 20 seconds or so. The lights also slightly dim as its shaking, and the rpms go up and down, as soon as I press the gas or start driving the problem goes away.... any ideas? spark plugs were just done recently. I have a check engine light 0430 for the cat. thanks guys...

 

daboss, how's the batteries state of charge. Perhaps it has a weak cell?

 

Hey daboss I recently had the same problem as you, I was wondering if you ever found the solution to it? I couldn't find any other comments below
