Im getting a misfire in piston 1 and i dont know where i should start troubleshooting. I changed out the spark plugs about a month ago but not the wires. Should i check the spark plug first or change the wires? Or is there somewhere else i should start.

swap the wires and see if it follows. if not swap the coils and see if it follows. if not, maybe your #1 injector is under-flowing the rest.

Check the same plug, It could be cracked or just fouled out.

Throw some dialetric grease on the coil post and plug.
