Random misfire: yes
Codes: nothing pertinent or helpful, so ill just say no
Fire was centered at the fuel rail. Most noticeable damage at injector harness. No, cat was not the source of the fire.
Compression..... good question! I checked compression. Cranking, all plugs out, throttle plate full open: 225 psi on all 4. (Too high, agreed?)
After that, I decided plugged exhaust. Dropped pipe at manifold (before the cat). No change. All symptoms still present.
