I'm having an intermittant miss on my I4 CIS injected GX engine. Cold-start,
thermo-time switch are both working correctly, new rotor, cap, and wires, no
vacuum leaks from manifolds or injector seals. It's timed about right. Fuel
pressure is good. I've pulled the plug wires one by one and it doesn't seem
to be cylinder specific. Do any of you experts out there know if this could
be related to the Hall sensor? Do these ever partially fail?

I'm thinking it's either the hall sensor or possibly a valve problem - but
the fact that it seems to cross all cylinders seems to preclude valves. Any
recommendations?

thanks,

Matt
