S600 2002 Mix fire in piston 10,11,12
I am having a mix fire problem in piston 10,11, and 12. The compresion is fine. I changed the injectors. I checked the electrical pulse in the injectors.I check the air leak tester. I checked the intake gasket for leakage. I cleared the codes and did a road test. The engine is running smooth but it has no power. Can someone help me????

I assume you have codes for (random) Misfire on 10.11.12.
You clear the codes and they return. Yes.
How have you eliminated plugs, wires, injectors? Have you tried swapping LH for RH bank components and determined whether code changes cylinder with parts?
Have you CAREFULLY inspected the engine wiring harness that runs to the injectors for any signs of deterioration?
So how do you define "No power"?
Sure there are no other codes set?

THE INHERENT PROBELM OF AN s600 WDB220 IS IN ITS ELECTRONIC IGNITION COIL, AFTER A CHANGE THE PART WILL GO BUST IN A SHORT PERIOD OF TIME, THERE ARE 12 IGNITION COIL, ONE FOR EACH CYLINDER, AND THEY ARE VERY EXPENSIVE. TRY LOOKING FOR A REPLACEMENT OEM PART. (BOSCH).

as stated above..it is most likely the ignition coil....if all the misfires are all on one bank probably the coil...if i remember right there is also an updated ignition control unit located on top of the intake...whatever it is it will be pricey

people are very wrong with the very expensive coil issue. when the cylinders are connecting such as urs are 10,11,12 it is the upstream o2 sensor. try that first i think you will be very happy that you fixed it with a 300 dollar o2 sensor than a 2,000 dollar coil pack

ignition coil
curious what the out come of your project was?
i replaced one coil cause it was miss firing in on cylinder.
replaced all the spark plugs.
got my car back from the dealership
3grand and a week later the other coil goes out according to the shop.
i dont believe it they said cause my oil sending unit was pumping oil throu the wiring harness into my coil.. theres oil but looking at the wires it looks impossible for oil to go through the wires like that....
thanks in advance....
