It is near time to change my oil. I need to wait to friday to get paid to have enougn money for filter and oil. Yeah my gas mileage still sucks I know that! haha. I also want to check the o2s to see if one of them is just crap! Also Going to replace fuel filter. And yeah I do maintance on my car! haha no worries. My Tour hasn't gotten good mileage(18.X was highest). But I do alot of hill/city driving.
How do you check if an O2 sensor is working? And which one does the fuel/air ratio? That is the one I want to check.
Also what happens if the EGR valve itself is clogged? wouldn't that set off a CEL? And do I need a gasket if I take it off to clean it? And what do I clean it with. Help me get back the Mileage! haha
