It could just be the difference between a truck and a van.  My van had 3.50 gears in a  9.25 rear.  Even though a van is a moving billboard, a truck creates a lot of vacuum via the bed.  That vacuum will eat some MPG.  I put a tonneau cover on my Dakota and gained 1 MPG.   A friend did the same with his full-sized Chevy and saw an increase of 3.
 
If all else is as it should be it becomes a crapshoot.

Ya.. that is how it is like in my Neon and Sebring...no filter.

I still think a hand held programmer is my only hope. The stock program sucks. There was a running program change for the 1998 and up truck. When it went in for a dealership check-up most got the new program flashed. Mine has an update of Sept 2000...

My buddy who gets 24 MPG out of his 1998 with a 5.2 has an update date of early 98. His never had the update program put in it.. He has to run mid-grade to keep from pinging. He says the extra mileage more than makes up for having to buy the mid-grade gas.

The program change was to fix the pinging on regular gas the 5.2 was having. They must have backed off the timing and played with the fuel map. I learned this from a Mopar Dealership.

I guess I could look through the wrecking yard and look at the flashing date on the front of the computer or get a programmer and change the program in the CPU that way..

I wonder about that too...

This truck did sit for a while.

Once and a while it sounds like it misfires.. not often..

I wonder if the cap may have a crack or something.

A new cap, rotor and plug wires, cleaned/replaced PCV valve are always good things to improve mileage, and if it hasn't been done, think of it as payment for all the years it wasn't replaced. Also, spark plug gap set to what is under the hood. The old ones used to be .032-.035, the newer ones are all the way up to .050 and if it is too small, well, mileage can suffer.

Another thing that can help mileage is cleaning and repacking the front wheel bearings. Had a 62 Caddy Hearse that I would drop mileage down to 15mpg, clean and pack the wheel bearings once a year and be back to its normal 17mpg (and she was 7950lbs empty).dana442011-06-10 02:55:01
