My #6 miss fired because of a bad wire

Either bad plugs/wires, or possibly the ICM. Seems kinda odd that it was only the rear cylinders.

could be a clogged cat. if the car has been loosing power slowly over time that maybe it.

and just what does that mean?

 

[BillBoost37]

He ..... uh.. yeah, what's that mean?

..I'll take a stab.....He had a cat strapped to the motor for sound effects. He let it loose and it's still missing?

 

[Travisgt2]

No I think he was saying his motor was ran by cats on wheels and he let one go but it didn't make a difference

Sounds like a bad coil pack. Pull each plug off and check for spark going from the wire to the coil pack for those cylinders. I use a screwdriver to do this but be careful you can get a nice shock

Mine where rusty and was getting a bad connection

You should find that, those rear banks are useless once they go missing...

I hate it when my banks go missing, especially all three. I just need to cash my check...
