Pontiac Repair: 1996 Grand Am missfire #1 & #3, cam sensor, lean condition

Question
96 Grand Am. 2.4L DOHC. Lost power while driving. Backfire in throttle body. #2 & #4 cylinders firing ok.  #1 & #3 are missfiring and backfiring like swapped plug wires would act. Actually runs better when #1 & #3 are disconnected. Can't see any carbon tracks. Good Spark. Good compression. Injected some gas into throttle body to check for lean condition, no help.  Area around catalytic converter, O2 sensor, and muffler glowing quite red. Swapped coils, no help. New plugs didn't help.

Answer
Only thing that comes to mind would be a bad ignition module or crank/cam sensor. The reason for the glowing exhaust is due to fuel dumping down it that isn't being ignited and if you have spark in those cylinders then it must be happening at the wrong time so either the module is interpereting the signal wrong or the signal coming in is wrong to begin with. Keep digging you're on the right track and it shouldn't be too much farther out of reach :)
