95 50 drinking gas

[ehn1993]

I have a 95 5.0gt recently the fuel consuption has increased Im getting about 7 miles to the gallon. The car has a fresh tune up,new tps,new fuel filter,the timing is dead on the money,and new O2 sesors. The only mods done to the car is a mac cold air induction,bbk underdrive pulleys and a cat.back system. Any advice will be welcome. Thanks

I would buy some "Sea Foam" and run it through the PCV hose like it explains on the can. You can get it from the parts store. You might have some carbon build up. I also use Amsoil synthetics in my vehicles. If your not using a synthetic motor oil your not getting all the power out of it and your missing out on about a mile a gallon better. Hope that helps.
