C43, Extreme shaking at idle
So I just had some minor work done on my car replacing the belt tensioner. See no relation with my prob though.
Drive to my girls place and everything is fine. I leave later on and when I started my car the thing was idling low it seemed and the engine was shaking the car alot. If I had an open cup of coffee it would have spilt. I gave it a little gas to bring the RPM's up and it smoothed out a bit. So I leave down the road about a mile watching the thing. When slowing to the first stop the car started shaking and bucking approaching a dead stop...I also noticed the led lights seemed to dim insync with the shaking/bucking...
After that everything was fine, drove 30min home without a trace. Let the car idle in the garage for a minute and nothing else happened.
ANY IDEAS??????

Anyone think it could be mis-firing of a cylnder??? Bad plug or bad wire possibly???
Called my tech and he mentioned that as a possibility. Also, would the scan tool pick up on a bogus wire or plug?
