Is that the engine I have then? I'm not up on the MB terminology.
I have 99 C230 Kompressor. Your tag line said you had a 98, so maybe it is the same.
But that's precisely what I was thinking about when I said tune up--plugs and wires.
If I can get under the supercharger and find the plugs and wires...I'll be set.

What's an MAF? I also thought I read that--even though it's all electronic ignition, that something in the distributor cap should be looked at.
thanks
