Help: 2001 Honda Civic LX, P0302 Cylinder 2 misfire

[JO8]

Need help on next steps. Trying to resolve P0302 code. So far I have replaced with new: Ignition coils, spark plugs, fuel injectors...any advice?

Try checking the compression in the cylinder. Could be a problem with valves, valve seats, or the piston rings.

+1
after that is checked
to be honest it
gets really hard to diagnose a single
cylinder misfire when you don't have a snap on scan tool.

Update: check the compression...all are 175. Also changed ELD to clear the P1298 code. No change...still cylinder 2 misfire...still need help.

Can you get access to a tool that will show if the power is flowing to the spark plug? I forget the name of it but I've seen it work. it goes in series with the cable and the spark plug and flashes every time a pulse is sent to the spark plug.
