still having problems heh.............looking at all your other post ive noticed you said you already checked the wires and plugs. concerning the plugs, you have never mentioned if you gapped them to factory specs...........did you? you also said you checked the dizzy, so, are you saying you checked the cap, rotor, and coil in the dizzy and they were fine? ive also noticed you never checked your timing...............where is it at?

What year is the car? in 1997 honda had a ecm updated for multiple misfire codes? you will have to go to the deal to see if it qualifies.

some 96's had an ecu update too...

WOW, this thread is still alive.

hey black sheep, you fix it yet? concerning your problem, i had a customer last week that had misfire problems such as yours. i swapped the dizzy with a known good one, checked, plugs, wire, vacuum, compression, timing, and it there was no change. checked continuity at at the CKF (crankshaft flunctuation sensor). there was continuity so it got replaced. no more misfires.
