Hello,
I have a 1999 Trans Am WS6. I put a new set of long pacesetter headers.
Since then I have problems with engine codes on the 02's.
After changing headers the original 02's code were coming up with heater problems. I bought 2 new 02's and put them in. Now the code came up PO134 read no activity Bank 1 Sensor1 twice. I swaped 02,s and still had the problem. I bought another 02 and put it in the bank2 sensor2. Still had the check engine light coming up with bank1 sensor1. I swap the 02's and the trouble moved to the other bank. . I found out both 02's I bought were bad. I bought another sensor and put it into bank1 sensor 1.
Thought that this would finish the job. Well driving again I got another code. PO134 again.Same code twice. It has moved again. The code I am getting are
po134 and po154.
Any else having this crazy problem.
Thanks
Wally

Make sure you don't have any leaks in the system. Also, are these GM or other O2's you are installing? Are you running rich, that will mess up an O2 as well.
