960 & S90 rough engine S90-V90 1997

I have a '97 960 and a '98 S90 with the same B6304 engines. They are running rough when idling, like they missfire and then recover. The local mechanic says that each cylinder has its own coil and he needs to find out which one is misfiring. Are these coils known to cause misfiring (both motors mileage in the 130k range)? Should they all just be replaced?
Thanks, doctim.
