Hello Gurus!!!

I have a 98 Firebird Trans AM, and it is throwing the above codes. This started when I replaced my passenger side AIR Check Valve. Is it really possible that All four of my O2 Sensors are bad, or is there something else. I would appreciate any help I can get.

Thanks

no, you likely created a problem, crossed hose or something with the repair for the air check valve, that's installed in the exhaust manifold isn't it? it maybe leaking, that would throw your 02 readings out

I also have a 98 TA and I have the same codes that have come up. I always get the 131 code. I was lead to believe it is happening because I put 5 gallons of leaded race gas in the tank. I was told that O2 sensors can not handle that.
