O.K. Guys, I spent a few days with it and found that it had a few problems coming together at the same time. First, the new cat, muffler, and tailpipe fixed the hot exhaust problem. Like I said before, the cat was toast, that is why it was glowing red. And the tailpipe had a hole in the top side directing hot exhaust at the left rear corner, that is why the taillight melted. Probably running rich on top of it didn't help. I found a couple of weak plug wires contributing to the engine running issue. But after reading your replies, along with articles on 2carpros website, I bought an IR Thermometer. Aiming the thermometer at each exhaust port and taking a reading, I found that the #1 and #4 cylinders were running about 60 degrees cooler than the rest. Since the #1 and #4 cylinders are connected to the same coil, I swapped out that coil. The car runs like new now. I am planning to do a complete tune up soon with all new coils, plugs, and wires. Big thank you to 2carpros, saturntech9 and jay4cars1 for your help diagnosing my car and getting me back on the road!
