For something that supposed to help the vehicle be better for the environment, we sure burned a lot of unessessary fuel completing the monitors. Hours worth of driving for no reason other than to complete the monitors so it could be smogged and registered.
I guess ill start driving it more then. I can pass with evap in new York, but I still need the egr to go away first.
