My '95 960 is not firing on cylinders 5 and 6. I have replaced the coils, injectors, spark plugs, and wires. I get spark from the coils, and there is power to the injectors. But the car runs real rough, and when I pull off the coils from those cylinders, there is no change. The same is true when I remove the injector connectors. When I do the same to each of the other cylinders, the engine gets even rougher, so I know that 5 and 6 are the problem cylinders.

The head gasket went bad, and so I tried a sealer just to see if I could keep the car running while I look for a replacement engine. I now get 150 lbs compression in 5 and 6 and almost 180 in the others. The pressure holds in all 6. There seems to be no leaking between coolant and lubrication.

I am going to switch the power stages but wonder if that will make a difference. Any ideas will be a big help. Thanks.
