On my way home from the Northeast Exotic show, my car started to sputter and cough blowing out a light black smoke. I went through 3/4 of a tank of gas in about 60 miles. Sounds like it's running too rich and blowing through gas. It would sometimes "catch" a good breath and smooth out only to begin a downward spiral with even pressure on the gas pedal. I was losing power, but then when I would "punch it" it would sputter up to speed while putting out the light colored black smoke. This was happening periodically for the past 4 weeks only in the mornings. I thought it was either bad gas or a clogged fuel filter (which I replaced at the beginning of the season). Seeing how much gas it used in the last 60 miles of my trip I don't think that's the problem. Idle was ok for the most part with a few stalls at traffic lights. It started right up however. Any ideas? O2 sensor?
