Default ok misfiring part 2. found a solution i think?

ok well ive been misfiring in cyl3 for a while, no matter what i did ( new plugs, wires, cap, rotor.) it still always misfired, well trew the code for it.
well i left the motor run, and puul the spark pug wiere off cyl 3, and it ran the same. pulle doff # 1 and ran diff. so does that mean i have a dead cyl, being cyl# 3??? or bent valves?

could be bent valves. Do a leakdown test and a compression test and see whats going on.

Good call. Fuel injectors and cylinder integrity are the next suspects.

Maybe if someone has an OBD-II scanner or a datalogger, you can get the injector pulse width and whatever other data from the ECU to see if the injector is even opening.
