Damn that's alot of misfires across the board. Did you check the plugs and replace those sh!tty coil packs. You are not burning all of the fuel that is being delivered to the engine, and it is probably dummping into your cat giving you the Catalyst Bank 1.

 

all the miss fire codes come at idle, when im under load i dont miss fire, and the cat is becasue both my o2 sensors are b4 the cat becasue for a while i didnt have one so its not a big deal. plugs are bradnew and working. i dont think i have any problems with the coilpacks. where could i get new ones

 

+ are there upgrades for the coil packs?

 

dont know if there are any, does anyone have a place i can get them

 

I believe lltek offers upgraded coil packs.

 

For a 1.8t, there was a recall for 2001 coil packs. See a dealer.
