2012 C250 Cylinder 4 Misfire Acceleration & Rain
My car shuts down a cylinder and shake violently as if in limp mode when under acceleration in the rain. It's always cylinder 4. I pull over. Turn it off. Restart the engine. Code clear. Runs perfect.
My dealership has seen the car at :
17,000 miles
28,000 miles
36,000 miles
48,000 miles
52,000 miles
It ONLY does this in the rain.
They cannot figure it out. Clueless.
They have assigned my case to a special ops team out of TN.
They assure me rain has nothing to do with it.
I assure them they are wrong.
I can drive behind a semi and floor it to recreate the same result any time.
Anyone else heard of this ?

Same problem with my 2013 C250 with 20,000 miles. Code P0301 misfire cyl 1 after following semi in rain. Problem would disappear upon restart.
Dealer checked coil and spark plug which were both good.
Dealer said newer software for M.E. was available (what ever M.E. stands for). They updated M.E. software and so far problem has not returned in 2 months.
