well... misfires (if there are real ones) - start with plugs, then coils... if plugs were not replaced within last 50Km miles, they can be replaced as a preventative maintenance, regardless if they are culprit or not... if the coils were not replaced within the last 100K, they can also be replaced under the preventative maintanance... if those things do not resolve the misfire, then the wiring to the coils... then, the DME...

what about those screenshots? you got them?
