So I finally got this code which surprises me that my front o2 has lasted this long since it got pretty damaged durning my headers install. I had to bang the crap outta my firewall to get the sensor to fit but damaged it in the progress...my question is has anyone tried running a 90 deg extension on the upstream o2 bung to keep the sensor pointed in another direction so it stays more protected or will it cause the sensor to not read properly? Id like to use one but if its gonna get bad readings then I guess I wont....has anyone tried doing this?....
