O2 sensors, tune, plugs and wires. check those things. O2 sensors will make your engine run way too rich

 

Damn 150 miles per tank is terrible.

My 93 with 3.73s gets about 17 mph in the city.
About 230 miles per tank.

When the transmission was going out and the stall wouldn't lock up, and it would hold each gear for way too long, it was getting 170 miles per tank MAX

The 95 with 2.73s gets 260+ miles a tank with mixed city/highway.
(About 60% city, 40% highway)

 

REALLY heavy shoes can cause this kind of Gas milage...

 

done it all already, 02's, pcv, IAT, plugs,wires, coil, fuel pressure okay, test fuel pressure regulator with vacuum tester...holds vacuum, fuel filter, tire pressure 34psi. when i was doing my coil, i had the intake elbow off and i opened the throttle blade and took a smell in the tb and i smelled some fuel in there, dont think thats normal that i know of, maybe its something my injectors or fuel pressure regulator(although seemed fine with the vacuum tester), or b/c she's running so really rich b/c of a clogged exhaust system, i have no idea anymore. and I keep my rpms below 2500 95% of the time. thats 150 city. oh yeah she's down on power.

 

Pressure test the Cat with a Hammer and a pipe.. That might help a bit.

 

I was having some issues with my car with leaky exhaust and something was throwing a code on my evap, so i used to only get 20-25 mpg on the HW.

Now my exhaust is cut and i can get 31 in the highway. Driving around the city i will get about 17 mpg, so roughly 270 miles on the tank in the city.

Stock exhaust is pretty restrictive, so you can prolly get some more miles out of your tank that way.

 

I get about 16MPG city and I don't know about highway because I have yet to really take a trip with it. Damn, maybe I need to just drive some where.
