I don't remember what's necessary to check an 02 sensor - I'm sure they could check it at the mechanics - They can check the voltage - maybe it's just reporting incorrectly.

And on a sidenote I got 33mpg on last commute - 33X miles on 9.89 gallons - I dig it. 78mph on the cruise and some city driving(maybe 20 miles of that)

 

I'd just walk.

 

oh thats a good idea to just check voltage..**** why didnt I think of that lol. so simple. Where can I find out what voltage it should be reporting?

 

run some redline fuel system cleaner in your tank its one of the best injection system cleaners on the market i use it and get 33mpg on the freeway and my engine has a supercharger

 

catalytic converter? :dunno:
