Hi, i own a 2000 maxima GLE. Recently, a Service Engine light came on. One thing i noticed when this happened was that i was losing ALOT of gas mileage. I used to get 24 mpg but now im down to around 17 mpg....so my question is, what can cause a service engine light to come on and make the car lose alot of gas?? thx.

just happened to me, go to autozone get the code read for free. Mine was an 02 sensor which is most likely the culprit in your case. That or the maf. If you write down the code there are some peeps on here who know the exact location of the problem.
