Can bad o2's affect engine/coolant temps and make idle bad? I have a feeling I know that my idle is a little jumpy because I found out both front o2's are bad. Can the o2's in any way affect engine temps, making my car run too hot? I don't have a 160deg thermostat yet, the rest of my mods are in sig.

Re: Can bad o2's affect engine/coolant temps and make idle bad? Bad O2's can make you run rich, and depending on how rich you run can cause a rough idle(not the good kind) are you throwing any codes

Re: Can bad o2's affect engine/coolant temps and make idle bad? According to the fella at Autozone, the codes I threw said I need both front o2's.

Re: Can bad o2's affect engine/coolant temps and make idle bad? Aren't the O2's in the back the same as the O2's in the front? They looked like they were on my 99 but I'm not positive. Maybe your could switch out the front with the back and see if that effected the idle.

Re: Can bad o2's affect engine/coolant temps and make idle bad? Once they degrade, there's no turning back. If you did any mods that richened the car up without tuning, say headers, the O2's probably took a beating. FWIW, I recently changed both of mine and the idle was incredibly smooth after that.
