I've had it with this horrible Gas Mileage! Idea's?

And here I go again - Goalie, before you go ordering parts, please - finish the mileage experiment. Don't do any math with the fuel gauge - it's only accurate to maybe +/- a quarter of a tank of gas, and you even said in a previous post that itt was showing only an eighth of a tank left, but only 11 gallons went in.

If you don't have the patience to wait until you finish this tank of gas, then go ahead and fill up now just like you did the last time when you reset the trip odometer and DO THE MATH... divide the number of miles showing on your odo by the number of gallons you just put in your tank, and that will tell you your true mileage. By the numbers you yourself posted before, you are getting over 19 mpg! (210 miles on 11 gallons of gas... 210/11 = 19.09).

Make sure you have a problem before you try to fix it. Problems that aren't really there have an annoying way of not responding to fixes.

Good luck!

You know, have you changed your driving style/ route/ schedule lately? Bad traffic, lots of starts and stops, even aggressive driving can affect your mileage.

I noticed when I worked late for a week that I got better mileage. (The drive home had almost no traffic).

I notice real bad fuel economy mostly on the highways over 70 mph. which is about 2800-3000 rpms.

I am still following your advice though, I am just giving it a few tanks to get the average number. I feel like im in a Math class again. lol.

I installed my new Fuel pressure reg yesterday. Pathetic how small that thing is. My idle is more regular now instead of so high and it seems to start easier.

Hopefully my mileage will gain from the new one.

A Thousand Pardons if this is a stupid question, but wouldn't driving with the Power button activated affect mileage? The location of the button is such that it could accidentally (or purposefully) be depressed by a passenger without the driver's knowledge.

I always drive with the power button on. I get 18 mpg.

Most Isuzu owners report that the POWER setting usually gives the best overall economy, and this is across the Trooper/Rodeo/Amigo/VehiCROSS line. Additionally, there is an illuminated indicator on the instrument cluster to let you know when the buttons are set to anything other than NORMAL. In a nutshell, the different modes adjust the shift points and torque-converter lock-up profile to suit your driving style or conditions.
