Hi all, I just bought a blue (ish) 96 Tacoma 2.7 4x4 ext cab 97,xxx with the 225 75 r15s :( . Anyways, I have been getting horrible gas mileage, like 13-16. I have got 19 at best one time. I have even been not reving over 2200 during shifts to save on gas.

So far I cleaned and lightly* re oiled my K&N and cleaned the MAF. CHecked tire pressures and installed new plugs. It runs really good, seems to maybe vibrate a little at idle, but just gets horrible MPG. When I changed plugs one of the metal connector peices inside a cap pulled out, so replacing those is on the list.

I have read on here about cleaning the throttle body and air/fuel sensors. How hard is this to do. I have searched but couldnt find any good how toos. Also, does the Air/fuel sensor need to just be replaced or can it be cleaned? The truck is in really good shape and I know it was taken care of by the original owner, I have all the paper work and maint record. I just want good gas mileage out of this with these little pizza cutters on it. Thanks in advance for any help

Welcome to TTORA!

If you have no check engine light, no need to replace or try to clean the O2 sensors.

I get bad mileage too, just part of having an older truck (I average 17-18, used to get 22).

You can try a can of seafoam: 1/3 into the intake, 1/3 into the crank case, 1/3 into the gas tank. Then change your oil within 200 miles. Search for seafoam on how to put it into the intake...and understand it will create a lot of smoke when you fire up you truck again.

Some people have said replacing the fuel filter helps improve mileage, but it is a real PITA to do on the 4-cyl engines, and although I have had one sitting on the shelf in the garage for 2 years, I have not taken the time to do it. :)
