    Fuel Problem?

    I was driving to work the other day and the car suddenly just bogged down, kept my foot down and then it accelerated then bogged down, over and over but never died. Today i got it home, I barely touched the accelerator and just kept it going. Here's a video of what it sounds like. I'm not sure whether it's the afm, fuel pump, fuel filter or some sort of vacuum loss. my neighbor said he smelled gas as i drove by in the morning. Notice my (chubby) finger doesn't move but the engine is revving then not revving..



    not sure if that link works but here's the youtube link

    Tee a gauge into the line that feeds the fuel rail and find out what the pressure is.
    The car makes it possible, but the driver makes it happen.
