I have a 95 dodge ram 360 and it is only geting 10 mpg. Im not getting on it at all and it wont improve. I have a k&n and a flowmaster exhaust. What could be causing it to get such low mileage. Any ideas of things to change would be helpful.

 

Checked your plenum yet? How old are your oxygen sensors? (ok, you should only have one..... if it's original, replace it with an NTK unit.)

 

The 360 under the hood isn't all that fuel efficient to begin with.

Besides the plenum and O2 Sensor ( I still need to change mine) when's the last time it got a good tune up and new/or cleaned air filter?

 

Id be happy if I could get 10 mpg's

 

I just cleaned filter and what do I look for on the plenum.

 

So You haven't even tried a TuneUp yet?

 

You read the first thread on top of the page.

 

NTK? Why not Bosch?

 

2nd gens don't like Bosch

 

Not sure anyone likes the bosch sensors.

NTK are good, as are Denso (OEM.....) The bosch tend to be slower reacting, so, you really don't get the benefit from them you would really like to have.
