OBD reads cyl 6 misfire
I have replaced plugs, plug wires
dist cap and rotor
replaced injector
compression check 148-152 all cylinders
replaced coil, all have power
still at idle- very rough
with acceleration runs smooth with mild ping

? Only thing I haven't changed was distributer itself
? Any suggestions

HI there,

I think that the ping is the clue to this problem, can you do a live data read and check ignition timing specs, also check for vacuum leaks around this cylinder.
