I got a problem to my sentra 93 XE. Last night when I started my car, I heard small noise in my engine, I accelerated the car, the noise became much louder. After finishing the acceleration, the noise became small again. But this morning, I could not start my car any more, I have to walk to the school. Someone said that I need to change the engine oil or trasmission fluid, I do not think so. Someone else said that I need to check my muffler and pipe system, I am not sure. I just wonder that I need to replace the spark plug or other tiny facilities on the engine. Hope to get help from you and thank you for your attention.
