City now averaging around 19 MPG since changing fuel filter.
no difference to highway MPG (26-29).
got 18.7 MPG hauling 1.3 Ton caravan over 455 miles.
All worked out by fuel added at pump and millage travelled.

I am in the PCM relearning process. I have topped out on highway at about 25-28mpg on the little readout. Last Tank before the muffler install was about 22-25mpg highway on the readout and full tank average of 16.7mpg.

My engine has a slight hesitation and PCM is figuring it out. I am hoping to get a better read on the current state of things in a few weeks.

My new engine seems to be running a little better. We'll see what kind of mileage it yields. I was averaging about 6 mpg before. That's all wheeling miles though. And DiangMaing, a couple of things, it's cool to see another NWI guy in here. Also, don't always believe the overhead. Mine consistently reads about 2-3 mpg higher than I'm actually getting.

I do a little better than 325 miles per tank, mixed driving but mostly heavy on the foot unless I'm cruising. Yesterday I did a 102 mile round trip to the pick a part on slightly less than 1/4 tank of gas... (From 3/4 full to just above halfway mark)

1993 4.0 Laredo stock with 235/75/15's

My timing chain is so stretched I'd swear I'm doing better than the window sticker advertised :D
