I have an 04 955 Turbo with a CEL and codes P0353 and P0303 (misfire cyl 3 and ignitiion coil cyl 3). I had multiple misfires and just replaced coils and plugs. I have tried moving coil and plug around and the codes remain exclusive to cyl. 3. My mechanic suggested next step would be to test continuity from DME to coil. I am going to give this a shot but I wanted to see if there were any other suggestions while I am at it. Thanks for any info.
