Is it only P0300 or do you have more?

at first it was several--then, only the one, 300---and, once i replace the wire--the problem went away long enough to smog--thereafter, four more erupt and continue to do so--even after i clear the codes--over and over paul here

Check the plugs, crankshaft position sensor, camshaft position sensor, etc. They all can set a P0300. Has the car really been serviced?

Hello this seems like the ground for the distributor that needs to be repaired at the left front fender or the distributor may need to be replaced.
