MAF issues
This place is a little quiet. But maybe I can get a hand here. M156 Engine in my CL63. Went to the car wash the other day. While I was in line; car started shaking badly and also cut off. I limped home which was only two miles away. I changed intake manifold, injectors and the plugs were changed less than 10K ago. got everything back together and left off the air filters and MAFs. Engine was smooth as silk... (Oh yeah) I plugged in the MAFs & filters; it srted idling rough. I plugged in the drivers side MAF and all good(Yes) then I plugged in the drivers side and "Random cylinder misfires" I unplug it, smooth again. I purchased I used airbox from E bay; same ****.. WTF?
1/24 well it all looks like its pointing to a bad 02 Sensor.

Good luck with the diagnosis. Super quiet in this forum, cars are just so rare. I guess you have some sort of diagnostic tool? I don't know how one could do without it nowadays.
