i have the same problem...but on a de

i used to get around 25-26 mpg.

now im getting 19-20

i have new o2 sensor, new plugs, new injectors, new cap and rotor, new wires..

would a new fuel pump affect excessive gas consumption? would an egr code affect gas consumption as well? how do i check if the injector is stuck open?

i didnt check the timing after i replaced the cap and rotor...do i need to do that as well because i don't seee the point in checking the timing if i didnt move/rotate the distributor.
