Hey everyone! My 2007 Nissan Sentra SER has been loud lately, like something is wrong with the muffler or the exhaust or something. It kind of smells like gas sometimes, and I have been getting poor MPG as well. It's due for an oil change and probably a new air filter,but that doesn't explain the loudness. Does anyone know of any place I can get it checked out cheaply? Or any place that offers a payment plan?
Thanks!!!
