96 LE - Bad Gas Mileage, Weird Noises.

Hello, i am new to this forum and the pathfinder. I just got my 96 LE with 92k on it. I love it but i have been experiencing terrible gas mileage. I get around 10-14 mile per gallon. I dont really think that i should be getting that bad of gas mileage. I was wondering what might be the cause of this, do i need to do the 105k timing belt service or is this something totaly different. I also experience and strange sound coming from the bottom of my pathy that sounds almost like a continual ringing. It sounds like something that is moving is rubbing, but not grinding and it makes a strange almost high pitch noise. I have no clue what it is. Any Suggestions on the problems mentioned above would be very helpful. Tank you.

Have your ECU codes read to see if there are any stored error codes. Sounds like the O2 sensor/sensors may have headed south on you. Those will give you terrible gas mileage if they quit working. The timing belt is a MUST, if the belt breaks your engine will eat itself for lunch internally and then require an expensive rebuild or new heads. The ringing noise from underneath is most likely a heat shield vibrating against something else underneath. That happens all the time.
