As an attempt to remedy crap fuel mileage I took a look inside my throttle
valve housing (I've done everything else I could do..........replaced the
following: 02 sensor, both temp sensors, thermostat, H2O pump, plugs, wires,
distributor and rotor, air filter, cleaned FI grounds) and notice an oily
gas puddle inside of it.  WHY WHY WHY...........is it supposed to be like
that????
there was also a bit of the same inside the AFM......
