Re: Red-glowing cat!

Old rule of thumb: "fuel cools." A rich mixture burns cooler than a
lean mixture.

Not too long ago I sucked crap into my fuel system (suspect it was a
piece of my deteriorated fuel pump boot). Stopped me up but good.
Literally limped back to the house with a cherry red exhaust system.
Eventually the obstruction made it as far as the accumulator -- hummed
like blowing across the lip of a coke bottle. Obviously my little
engine was starved for fuel (killed it once in transit). I replaced
EVERYTHING in the tank, filter, and blew out the system, but converter
continued to glow. Gutted converter, now car is happy again. Didn't
see anything obviously melted in the honeycomb, but it was pure white
without a speck of soot. 

Check your fuel tank pickup screens. You may discover one quadrant
torn or missing altogether. If so, you may have sucked crap into the
system.

*might* have been a very close fire, but I'm puzzled to what to look
for? Why did the cat act like this? I have never experienced this
before...let me also at that it sputtered when I drove it, but I think
that's mainly bad spark plugs and/or condensation because of the
winter climate we have here right now.
