Catalytic converter gets red hot??? Very late ignition timing or lots of unburned fuel in the exhaust. What sort of readings do you get in diagnostics at warm idle in park? Almost all the readings will give some possibly useful information so a snapshot of what they are may give a clue.
yes, had the 10VDC. the 9, 8 and 0 where the reading from sensor feedback. plan check fuel and piston pressure tomorrow. also got some gas dryer stuff just incase.
