Take the battery cables off the battery, hold the ends together for 10 seconds then attach them to the battery and see what happens. This will reset the whole vehicle.
miss fire was jumping all around before
will try that..why would noid light?
no codes? even if you can keep it running with carb cleaner or something?
Not sure about the noid light. IF that does not work, I would be tempted to try a crank sensor;.
havent tried to keep running with carb clean
spark ok and noid flashes why crank?
may be worth a try to get the RPM high enough so some of the tests can run.
Weak signal may be firing at the wrong time.
