I was thinking it was wet ignition, I removed the cap and sprayed a little wd-40 in it, after that I pulled a plug to see if I was getting spark. It was so I was assuming the ignition was fine. The wet (fuel) plug made me think it was getting fuel, but not sparking. So if the ignition is firing, there's fuel, and the air intake/exhaust is OK, the bugger should fire up, no? Intermitent electrical gremlins somewhere in the OVP or fuel relay circuitry? Damn I love my benz, just not this week
