C230 kompressor missfires.
 

i have a c230 kompressor that is missfiring in cylinders 2,3,4
i have changed fuel filter, cylinder 3 injector, temp coolent sensor, and a full tune up.
when i change the injector problem went away for a week and came back.
my check engine is on all the time and car has no balls.!
there are fault codes as such.
1- cylinder 2,3,4 missfire and fuel defficient
2-temp coolent sensor
3-cam shaft sensor
i have given up as merc benz user cant really figure it out

This sounds like a bad fuel filter. After that, test your fuel pump.
