Cylinder 6 misfire - need ideas!

2002 CLK55 with 33,000 miles. Check engine light is on. Error code reads Cyl. 6 misfire. The car is running very rough and you can smell excess fuel in the exhaust.

So far I have tried plugs, wires, #6 coil pack, and a new mass air flow meter. Car still misses.

It seems to do better when warm, but it still is not right.

Any ideas??????

Did the electrical supply connector to coil for #6 cylinder check out okay?

It sounds like you've gone through all the other parts - I wonder if the wiring harness for coil supply is still in good shape? May be worth checking that out.

Traced the wiring all the way back to the computer with no problems. It is looking more and more like a defective computer.
