    I have a friend who has an 88 chevy with a 305, the truck is dumping huge amounts of fuel down ththrottle body, any ideas. I unplugged the 02 sensor, and it didn't change. Its not flashing a code, although he said the light did come on at one time. Nay help would be great.

    Start by having the computer read. Advance, Pep Boys, and Auto Zone will read the computer for free(at least they do in my area).

    Sounds like a stuck fuel injector or bad throttle position sensor...
