2004 Nissan Sentra Q&A
2004 Nissan Sentra Question: Why am I getting poor gas mileage in my wife's Sentra?
I just purchased it used about 3 weeks ago. It has 74500 miles on it and we are only getting about 20 MPG. I put some seafoam in the gas thinking it would help. I installed a set of new correct plugs and checked the air filter and tire pressure. All good. What else can I check and possibly repair to improve the mileage? - grallsup
i would change fuel filter and clean the injectors, clean throttle body - ebans777
