Bad gasmileage
ok guys i have a ranger with the 3.0 in it. i usually get around 15mpg in the winter, and 18-19 in the summer. well right now i have been getting ridiculously low gas mileage. im gettin like 11-12mpg , my cat is clean, and my tire pressure is at 38 which is what i always run my ac isnt even plugged in because i hate the drain on the engine when its running. so do you guys have any suggestions to help me out

Re: Bad gasmileage
What year is this truck and how many miles? IAC shouldn't be doing much of anything when not at idle. Start with the basics (and cheap) and then get more complicated.
- Replace or clean air filter (done) - Clean MAF (procedure in the How-To section) [free!] - Clean the throttle body (procedure in the How-To section) [free!] - Clean the IAC while you're at it (Why not, its there) [free!] - Replace fuel filter [cheap] - Make sure fan clutch isn't seized (can you spin it by hand with the engine cold and off) - Replace spark plugs with Motorcraft of Autolite brand only!!! Seafoam treatments may or may not help. If you choose to do that, do it before changing the spark plugs and you will need to do an oil change within 100 miles. Search for seafoam on here for lots of info: - 1/3 can through the brake booster - 1/3 can in the gas tank - 1/3 can in the oil |

Re: Bad gasmileage
I run 40 psi front and rear, i found that is the best for bumps/gas mileage/wear on your tires.

Re: Bad gasmileage
I thought it would be better to have less pressure in the winter since it improves traction...

Re: Bad gasmileage
alternator blew up on friday so i think that might have had something to do with it too if it was going and locking up

Re: Bad gasmileage
Nah you'd know it. The belt would squeal and break. I think that might be a coincidence.
