Header SES Light

[Smitty]

I got my headers and high flow cat put on last summer...and since then my ses light has been on.....ON occassion the light will go off by it self, seems to be on cool days only or easy driving. Then it will come back on on a hot day or hard driving
The code is reading the right bank and left bank our to lean.......but i took my car into pontiac and they said it was all fine......that it was b/c of my headers and the airflow running through them was to much and the o2's cant get a good reading..so it throws a lean trouble code.
Does any one know how to fix this problem or were to look to find an answer.....i tried to search and look in the archive didnt find sh** to fix it .

I think the only way is to get O2 sim, I have high flow cat and SES has been on since the day I installed it. :mad:

Mine has been on since the headers also. to fast air flow through the EGR.

the only down fall to o2 sims it that the are for after the cat......my ses light is reading the header o2 sensors(left bank and right bank to lean)
Sombodey suggested moving the o2 sensors in to the collecter of the headers any one ever done that? Does it work?
