the problem is suddenly gone
I don't know how it disappeared but it might be because yesteray I put a bottle of injector cleaner then took the car around town .
Yesterday it ran very bad and then I parked it in the garage. Today there was no hesitation or stalling right at the start.
I forgot to mention on top of the post that the problem appeared suddenly after I let the car rest for 3 days. I usually never let it rest for more than a day.
It was definitely not a spark plug or voltage problem because when I pulled off the connector 1 inch off the spark plug I could hear very loud noise of the spark passing from the connector to the tip of the spark plug.
I may never let my car sit for more than a day again because I am sure the problem will come back if I do so. I only want to drive my Mercedes.
