…. I changed the factory installed air filters!!!

Actually, I'm not positive that they were factory, but they did say Mercedes Benz on them..... and they were black and full of crap. Dead bees mostly.

The surge is gone though, seems like it is idling dead smooth now. Before it had an occasional stumble.

I also did the Crank Position Sensor, the Cam Position Sensor, Oil and filter change, and a new Cabin air filter.

Just hit 61,001 miles.
