Hey everyone I have a 2002 c240. I’m having a few issues with it.

1 engine has a misfire really bad. Pulled the codes and says cyl 3-6 misfire and then random misfire
coils plugs wires and maf have all been changed

2 the car will not shift gears. That is to say if I run it for 5 min the indicator on the dash will not show what gear your in When going from drive to park you can only go to neutral then you have to shut the car off so you can get it in park If I rest the codes then it works as it should.

honestly I suspect the ecm to be bad or a huge wiring issue. There are also little things like the speedo says the low beam lights are out but they are not the horn works when it wants and a few other things.

when I pull the codes just about every on the car throws at least 5 codes some throw 20 or more.


any thought on this. ??
