Well I have a random missfire when drivin around and at high rpm's the oil pressure fluctuates. I have good wires and everything on, good plugs, cleaned the cap and rotor. Im leanin towards a bad distributor. Maybe too much play in it? That would cause erratic oil pressure at high rpm? Its not bad, it bounces around from like 60psi to 55psi around 3000-3500 rpms when cruisin at steady rpm. At idle the oil pressure is solid at 42psi when warm. Its only higher rpms. I have no tach so Im guestimating these rpms.
