Cylinder 2 Misfire and dashboard lit up like Christmas tree

[Mugen203]

My 2018 Honda Civic S.i I have been having been showing symptoms of weird idling recently of dropping a little below 650 rpms randomly and my car not being able to use hill assist and sport mode, and that theirs a problem with the Break, and traction control, but still runs fine until recently I left work my car could barely get past 20 MPH, plugged in my sensor to ODB port and it says I have misfire in cylinder 2, my friend thinks I have a wiring issue, I’m hoping it’s just spark plugs and coil packs, can possible bounce some ideas off me that could help me confirm this

The old diagnostic trick of switching coils and seeing if the misfire moves to another cylinder would seem in order here. Also... check if any furry little marmots have taken a bite from your wiring. Most of the other errors, IMO, would be subsequent to the misfire.

Thanks, it was the spark plugs but now I gotta look at the wires and see what’s up with them when my 10thgen s.i only has 30K on the clock

Rodent damage maybe. Rats like to get in there and chew them up.
