Lets see, I had new Bosch plugs put in last week when I had it tuned up, I did the plug wires myself the next day. I am going to check for vacuum leaks this weekend and check the fuel distributor as well, if all else fails, I'll spring to take it to an actual MB mechanic have them run some diagnostics on it and do a compression test but I'd much rather try and figure it out myself.
It's not burning oil, I don't see any blue smoke when I start it up in the morning or when I accelerate. It was a quart low when it got tuned up.
I'm stumped. Right now with everything else that's going on, my car has officially been moved to the bottom of the food chain- at least until I've got time to spend dinking around with it.
