I already done gave her the eyetalian tune up an blew the soot out, 45 to 75 mph uphill grades (well central florida uphill grades), tried to get the catylitic converter thouroughly warmed. Not sure how usefull but it was entertaining. And the good news is I sold the Honda and now have cash in hand for a fishing boat. Which is the reason why I bought the Jeep in the first place. Bada bing.

have you cleaned the MAP?

Yes indeed, it no longer looks like a charcoal briquet. It was quite the little sooty nugget. When I pulled it out my buddy said "holy shi*". Cleaned it with some ether.

If it looked like a crispy critter then you probably have clogged arteries as well. I have seen pictures here that SCREAM clogged. A little dance at low speed does not clog up a MAP. Conversely, it takes a while to erode all that crap built up.
You should see a dramatic increase in mpg's if you did not destroy the MAP.
Congrats, probably the one best, cheapest fuel mileage improvement done :pepper:

It's been running for a few days so I think the sensor is all right. It was cean when it went back in and ether always smells good!

Rpm below 2000, you have got to be kidding me, do you shut off the O/D? Give it some fuel, these are high RPM diesels. I want mine above 2000.

Nah, I like driving slow

I am at half a tank, getting close to an update. Anybody want to play a game? Try to guess what my mileage will be in this tank. Last tank was 16.9. Since then I have:

1) Changed air filter and motor oil.
2) CLeaned MAP
3) Unplugged MAF (ORM Mod)
4) Verified tires are properly inflated, aligned and brakes are not hung up.
5) Consistently engaged in conservative driving.
6) Discovered my odometer is low, miles travelled are 4.02% higher.

This is 70% city driving, Florida, AC on.

If you cleaned out the crud 23mpg
If you still have residual internal guck 21mpg.
If you are dancing with the stars 29-30 at least.

Measure out oil, dipstick may be incorrect.
I idle to keep my dogs cool, the kids can get a water or get out. 22-23mpg.

My guess is 16.8.

I cleaned my MAP thoroughly, checked/lubed all 4 brakes to make sure there weren't sticking, switched to all synthetics, removed my engine fan, increased the pressure in my tires, etc. etc. etc. And I got exactly ZERO extra fuel economy driving the same route with the same driving style.

All i know is my mileage is TERRIBLE when she is cold and good when she is warm and excellent on the HW all nice and toasty :JEEPIN:

I average 12.5km a litre in town and 10km or less on the HW.

How much is that in American?

12.5 km/l = 29mpg
10 km/1 = 23.5mpg

I presume you mean that you get 12.5km/l on the highway and 10km/l or less in town.

22.9. Officially I am now getting 23 mpg. I think Fastrob was first with the correct answer. You win a significant amount of praise! And a dancing bananna!

:BANANA:

Woops - actually its 12.5 l/100km in town and 10 l/100km on the highway!

Late night postings not a good idea

Okay, well, your in-town mpg would be 18.8 and your highway mpg would be 23.5.

FWIW, you can type this stuff into Google and it will do the calculations for you. I just typed "12.5 litres per 100 km to mpg" and it gave me the answer.
