so i got my new exhaust put on while i was on my mid tour leave from afghanistan, as soon as it happened i popped a trouble code P0152-O2 SENSOR 2/1 CIRCUIT HIGH, so i replaced both upstream o2 sensors and that didnt fix it, well im about to come home from afghanistan for good and im trying to figure out what the problem is, has anyone else run into this aftr installing headders? my upstream o2 sensor wires are pulled tight so i ordered some extensions for those, any advice or oppinions would be usefull

 

You could always cut and add wire to those O2 wires but if you already have extensions on the way then I wouldnt worry about it. Have you checked for exh leaks at the gaskets? What type headers are you using BTW?

 

running the TTI Long tubes with their y-pipe the difference over stock is amazing will post some pics of it when i get back to the states, just hoping i didnt jack up the wiring harness or anything
