Hi I have a 4cyl 99 ranger and its ruining my pocket, it used to do 20 to 21 highway and now its doing 16 miles per gallon. I run it at an avg 50-60mph and it still burns a lot of fuel.

any suggestions?? thanks

 

How many miles? A tune up may be in order. Plugs, wires, fuel filter, clean maf, clean throttle body, etc.

 

Time for a tune up and check tire pressure. Lots of things can affect gas mileage. Are you carrying more weight in the truck than you normally would?

 

x3 on the tune up.

 

It has 190k miles

 

Nope I just carry my jetski on weekends nothing else

 

Heres a list ive compiled from threads like this:


Oil / filter change
fuel filter
air filter. dont need KN just solid brand
plugs & wires
serp. belt with new idler & tension-er pulley
Clean MAF Sensor
02 Sensors
Change Tranny Filter and Fuild
Change Rear end Fuild
Dump a bottle of Seafoam in her
Coil Pack
Bump up tire pressure
Clean your throttle body and manifold
Open up the air box
remove A/C all together
clean IAC sensor


you do this and itll make a world of difference, little in power but definitely in MPG!

 

start with a air filter, clean the intake and MAF sensor. do a bottle of seafoam then replace plugs AFTER seafoam. Fuel filter is a big one. Start there. no need to go to too much extremes.
