I get 7.0 mpg city, 8.0-8.3 highway!! No matter how i drive( heavy foot on gas pedal or light foot) i am getting almost the same MPG!!!! Ive changed spark plugs! What other things should i check!?? EGR and Oxygen sensor could be the issue?? How can i know if the oxygen sensor needs changing if EGR needs changing?? Wouldnt o2 sensor work bad because EGR is bad?? Please help:( thanx

Are you calculating those numbers by hand or using the overhead computer?

Rusty muffler bearing, sticky clutch belt, idk...

On a serious note...

Check wheel bearings for stickiness, injector cleaner, sticky brake calipers, MAF

You definitely have a problem.

I got better mpg than that in a 79 Ramcharger on 40" swampers with 4.56 gears and a 500+ HP carb'd engine (see avatar pic).

Let us know what ya find out.
