okay, i thought i was finished asking questions about this, but i guess not. i keep getting the cel's. i check the codes, now i'm getting p0153, p0133, and p1000. i know what the codes stand for, slow o2 sensor response, but what's the next step? it seems weird i'd get two bad sensors at virtually the same time. i probably ran the off road x for 6 months without getting a code. now probably a month after installing shorty headers i keep getting codes...the positions of the sensors are virutally the same.

is my only option to put the stock h pipe, air kit and original tune back in and take it to a dealer for warranty work?

any help or advice would be appreciated, thanks.

 

have you gotten a tune since the headers, did you installl the headers yourself or a shop, do you have a leak and what brand headers

 

frpp shorties, definitely no leak. the only tune is the diablosport airaid tune with insert removed. all i have done is disable the catalyst temp sensors and adjust for tire size. headers were installed by a shop.

 

rojizo, have you considered getting
a custom tune (for your mods).

if you have no exhaust leaks, then the
tune just might be the problem, as
howarmat and mustang both suspect

 

I'll talk to PSI tomorrow and see what they say. perhaps the first step would be to put it on the dyno and see what it's doing along with the a/f ratio check.

really, thanks. i appreciate it.
