Does the first code just mean the cat isn't working correctly (if one was there) and the second one saying the 2nd o2 sensor isn't doing it's job? Just hoping it's right and didn't fry an o2 or anything.

Looks like the spark plug fouler trick didn't work out on my car. I used part number 42002 and drilled it 1/2".

yup, I get that once in a while too but I also did the fouler trick.

How often does it come back for you?

brancky3, did you use two foulers, one drilled and one non drilled, both screwed together?

like so:

not yet! alan, what size is that testpipe? i was only able to fit one fouler on mine (atp 3"testpipe). there was no clearance for it.

this is from a honda or another jap. car. i think it's either 2" or 2.5". do you get any codes outkast?

if you'ze in so cal and need a "hook up" for passing smog, meet me on the corner of hollywood and highland tonight at 2:15 AM.

I think you can only fit one fouler in our cars. I have the longer fouler of the 2, the 42002. Maybe I should try drilling the other one I have, except leave the very end of it so it only has the tiny circle on it. Obviously the one I am using now isn't working too well, CEL came back after about 20 miles tonight.
