Help needed with a misfire

The code shows the cyl#1 misfire counter has exceeded the misfire threshold some time in the past so it tripped the code. The misfire counters on the second screen is the real-time value of those counters. 0 means no misfire at this instant.

OK thanks for that, makes sense when I think about it! Guess it is No 1 Coil and plug check time then? No CEL though, but I can definitely feel "something is not right", the idle is a bit lumpy too. Do I assume if it was bad fuel then it would bring up issues on all cylinders? Annoying really as plugs and coils are not 1000miles old yet, not long since I replaced them.

My first guess would be coil and plug on cyl #1 as well because bad fuel should affect other cylinders too like you said. Unfortunately cyl#1 is in the worst location to check. I think at least you should make sure the electrical connector of the coil is fully seated (i.e., should hear a click when connecting it).

+1.  A lot of people get tripped up by this.
