The Best 2007 Audi S6 Check Engine Light 2023. Engine shaking is often caused by a worn spark plug, bad ignition coil, ignition control module (icm), or a bad catalytic converter. Thinking this was probably a glitch i turned it off, let it sit for 5 mins and then started it again only to have the same thing happen again.

Made it home fine and let it sit for probably about an hour. Web recently i got the check engine light on and i did some search most people said it was a vacuum leak but i can hear the leak but can't find it. I now have a cel.
