neons had a problem with oil leaks from head gasket. that oil soaked the
harness under the exhaust manifold. the crank sensor wiring is in that
location. the computer monitors the crank shaft speed to determine
misfires. if swapping the plug wires 1 and 4 doesnt change the misfire and
you have equal compression on all cylinders. that would be a good place to
look. that part of the harness is easy to repair since there are not that
many wires in that branch. also had the same problem near the cam sensor,
your problem is more likely to be from the crank then the cam area. the
wires would become fused together from the heat and oil the insulation would
break down and cause an intermitant stalling condition when hot. also check
your crank sensor for any leaks out of the connector. crank sensor is
located under the alt.
good luck.
