99 ML 430 Problems HELP?
I have been driving this with this problem for a while. Every time I start it, it continued to turn over then would start. I had it hooked up and they said it was missing on 3 cylinders all on one side.
I paid the Mercedes Mechanic online to tell me it is the catalytic Converter but everyone tells me if that was the case it wouldn't go over 55 mph.
It used to bog down at 65.mph
I then had the spark plugs replaced and it still had the same problem starting but sometimes it starts just fine and now runs great.

Now recently it died as I was almost to stop and it started up and I parked it, a few minutes later I tried to start it and it would just turn over and over, but no start.

When I pulled the spark plug in the front it started up fine. Plugged it back in. It wouldn't start. Unplugged it then it started.

Put a new fuel filter in and it started up perfectly then parked it and went to start it a few minutes later and again it wouldn't start. Next morning, it started perfectly and ran fine at start up and while driving for a few days.
Today it started fine then I was almost to work coming to a stop and it died. Now it won't start again. Tried the spark plug and that didn't work either.

ANY ADVICE?
