Cars with Kooks

anyone get the P0430 and P0420 codes

"Catalyst system below threshold (bank 1 and 2)" or something like that?

comments?

this is similar to when I had my HF cats on...but that went away

this the same thing?

 

Isnt that the catalytic efficiency codes?

My Jeep used to spit those out all the time.

 

I guess the question is: has anyone running LTs and HFs ever NOT gotten these codes...

 

these are not stock cats lol

these are the Kooks cat'ed midpipes

so to edit yoru question

has anyone running Kooks and Catted mid's got this code before?

 

fixed it

 

so then the next question is...

once you get them...how do you make them go away LOL

 

on the jeeps ur screwed

 

Turn off the rear O2's with Predator.

 

Will I Pass OBII with that?

 

No. because with the rears turned off OBDII is not going to report in the "ready" state. whatever that is... something like it needs for some set of signals to show as operational.

So did these just pop up where it's been good for a while before? If that's the case then you can figure you were on the edge and you might try spacers/anti foulers. Seems those work for some people and they work for a while for others and they don't work at all for still others?

 

I got those 2 codes once, a year after I hollowed my catts,go figureLoL!

 

Antifoulers...2 on each side on the rear 02's.Need to drill one to 7/16" and screw it into the other then screw both into the pipe and put the 02' in.....codes will go away.....if not stack a third.

 

Thanks big daddy!

will do.

 

I dont know if this will work with the jeeps but on the trucks you can just tie the down stream sensors to the frame and no codes...just plug the holes...but this may just be a 10 thing..

 

so what does the antifouler do?

from what it looks like it just pulls the 02 sensor further away from the headdres?

is that right?

 

turns out the 18mm AntiFouler is much more difficult to find then I thought...

14mm's are cake to get...not so much 18mm lol

 

Go to Autozone and look in the "HELP" section.....I forget the part #

 

Just called autozone to make sure they have it....its in Beacon so I am about to drive up there to get it....just was hoping it was at one of the stores closer to my house lol

I want the tapered 18mm non fouler right?

ill also get some anti seize and a 7/16's metal drill bit while im there...

anything else to add to the shopping list?

 

nope,thats it

 

So 62 1/2 miles later....I got everything I needed lol...autozone only stocks ONE package per size at 18mm....will install tomorrow...maybe if im ambitious ill ATTEMPT a how to (unless there is one and im a dumbass LOL)....or im a dumbass and theres not one....there i said it...
