Engine Performance problem
2005 Mazda RX8 Two Wheel Drive Manual 50000 miles

the car was very low on gas but running fine. I stoped at the gas station filled it up but when I restarted it, the car had no power and was berly running.I drove it a mile or two and stoped and the caddilac converter was bright red and glowing. It sounds like the caddilac converter is clogged but the exaust is flowing good. I think it is just bad gas but not sure. What do u think
