A red hot cat certainly suggests excess fuel.

Can you pinpoint the regulator as the culprit? Do a fuel pressure test and sniff the vacuum line for traces of fuel (you should find none). If you have a konwn good regulatoir (same part number), then sub it.

Perhaps the oxygen sensor has failed, or -- if your car is the right (or wrong) year -- the engine harness has crumbled, causing some hort between adjacent wires or to ground, and this is upsetting the AMM reading and/or performance. In other words, maybe a good AMM is sending bad readings to the ecu because of failed wires.
