1996 Honda Civic 1.6L I have installed new cap,rotor,coil,plugs,wires, and dielectric grease. It runs OK but it seems like its lacking power, so while the motor was running I pulled 1 plug wire at a time. When I pulled off #4 plug (closest to the distributor) nothing changed in the motors idle. When I pulled #3, #2, #1 it wants to stall out. What would cause my cylinder #4 to completely missfire?

That's a good way to over stress and ruin your new coil.
