Finally removing my LT Headers!

[VSTOLsnake]

Well after 1 year, (3) 02 sensors, 2 MILS (I didn't need) I am pulling off my LT Headers and catted X-pipe because of the P0133/P0153 code. No leaks, no bad wires, 02's are good, out of ideas. After hearing of about 100 people with the same problem, I'm going back to stock. Anyone have any luck fixing this...alot of people say they fixed it but never report back that thier "fix" didnt work.

Thanks

those diag codes can be turned off within a custom tune, did you try to have a tuner eliminate those codes for you? My Longtubes have the original rear O2 sensors placed into the headers after the cats, only to make the DOT happy, my tune ignores them, no codes.

Hey if you're taking off your Long tube headers, I buy them for a reasonable price.

I have this same problem with my GT. Does your Cobra surge or buck at a certain rpm under light engine load, i.e. driving around town. I have had this problem for two years and it throws the same codes. The kicker is it didn't do it until I had the LT's in for almost a year. Kinda weird.
