use spark plug anti foulers instead the O2 sims don't work on 03+ usually.
The new cars computers run rich and then lean on purpose to test rear o2 function. The sims report back a voltage range that is acceptable to the ECU. When the car runs its test the voltage will not change and you will still pop a 0420/0430 code.
I have a NEW in the package set of O2 sims PM me a address if you want them for free... they will be worth what you paid.
