Hello.

At first, my english are not that good as it should be, so I apologize for that..

I have a problem with my Benz. To make a long story short, the problems starts often after I've been driving for aboust 1.5- 2 hours. The thing that is happening is that the engine starts to misfire. It helps when I shut of the power for aboust an half sec, then the car runs again for a while.

I've changed one coil, checked all cables, changed the sparkplugs and changed the "famous" overload protection relay (0005406745), but it seems to be the same problem.

Maybe someone of you can help me.

/S
