Question Asked: My van's front catalytic converter heats up and misfires after 30 minutes.

My front catalytic converter turns red hot and cylinders 2, 4, & 6 begin to misfire. The engine code reads misfire in the three cylinders. There is very little exhaust when the vehicle begins acting up. I have removed the front catalytic converter but the three cylinders continue to misfire (no where near as bad as it was before cat removal) and the engine codes still reads misfire in cylinders 2, 4, & 6. The spark plugs have been replaced. Any suggestions?
Question Asked: My car began running roughly and has very little power.

The exhaust is white and one spark plug is covered in oil (around threads). I cannot really drive the car due to the lack of power. I replaced the spark plug and there was no change. Any suggestions?
