My 2000 Ram 1500 with the 5.2L has been getting awful gas milage latley. I've been driving primarily city latley and I've been getting 190 miles to a topped off tank. I've replaced the air filter and both 02 sensors, and it still gets this milage. I don't drive aggresive at all. What could be causing this terrible milage?

 

did you notice a change in power recently? you may have a clogged catalytic converter.

 

also dont forget a tune up u no the good ol' plugs wires cap rotor air filter check tire pressures alignment all that good stuff...

 

Another thing to look into would be a blown Plenum gasket

Edit: Of course I only seem to get between 10-12 in the city depending on my driving.
