I have a 94 Z28 with an opti spark distributor. I had it replaced
about 6 months ago along with the coil, ecm, wires, and plugs.
Recently, it started missing at low rpms. I changed the plugs and
wires (2ond time) and it still misses.
I now have the distributor off and the rotor looks terrible. No
contamination, but it doesn't look like it is not making contact with
the electrodes in the dist cap. Spark by osmosis??
In all my experience with traditional ignition systems the rotor
always contacts the electrodes, if not, replace the cap and rotor.
Is the optispark any different? Should it be this way?
I would think if it is not making contact, it wouldn't run at all.
