I have a 96 Bronco with the 5.0 and e4od auto. I have noticed over the past couple of tanks of gas that my gas mileage has dropped quite a bit and I was wondering what upgrades or fixes might be recommended to get better fuel economy.

Along with weight reduction is remove the rear passenger seat if you don't use it. You can always put it back in if you need to. Since you are thinking of re-gearing, keep the gear ratio as low as you can stand it with the tires you are going to have mounted as long as you keep in the acceptable RPM range suggested for the engine.Assuming the CEL is not lit;Basics:
Check tire pressure -
what type of tire do you have & what PSI is in there?
& have you changed to larger diameter tires (32's 33's etc. but not calibrated the PSOM?
Reduce cargo weight (I took out a lot of tools and junk I've been carrying around)
Ck air filter
Pull a plug or 2 and ck; altho the factory platinums are "good for 100K miles" they do gap wider over time.
What is the PSOM?have you changed to larger diameter tires (32's 33's etc. but not calibrated the PSOM?
Uh Oh, Me too, I have a 95 xlt and have 33's I have not recalibrated anything. Is is that important? What is it? Where can I find it? How do I do it?
JoeWhat is the PSOM?Is it in a '90 302?
I went from 31`'s to 33's
Do you have a link to instructions for calibrating it?
If you have not corrected your odometer, you need to correct for the difference in tire sizes when you calculate gas mileage.its about 3.19 here. just do a tune up. new dist. cap. new plugs, new wires. oil change, new air filter. and fuel filter. i had 31s and got about 10 mpg after that. then i added 33s and went back to 7 again.
yoda got skillz.If you have not corrected your odometer, you need to correct for the difference in tire sizes when you calculate gas mileage.To do so, divide 33/31 and multiply that 1.0645 % times your calculated mpg so a 7mpg recalculates to 7.45 mpg
