  • 02 Sensors Bad

    I keep burning up 02 sensors after my cat anybody got any ideas why, my cats only got 40K on it, i can't see why it would be bad and its still solid no rock sounds or anything. But this is my second 02 sensor in the past month and they aren't cheap. I checked the ground also to see if it was hittin bare metal anywhere and its all solid looking to me..... Any ideas would be greatly appreciated. thanks guys/girls

      runnin anything from mid grade to 93 octane no race fuel..... But i found out today i got a couple more codes as well i threw a P0174 and P0171 cylnders are gettin lean condidtions. So i'm replacin the 02 senor cleanin the MAF sensor/ maybe replacing and check the entire vaccum system for any leaks i'll let ya know what happens from there
