    I don't even know where to start..

    I'm crusing down the road going about 40 and my gas light comes on, but I know I gave gas in the tank. I still pull in to a station fill up and go on. Then about 2 miles down my gas light cones on again then my ac stops cooling, and my engine starts reving but does not pick up speed.I pull to the side get out and can hear the car bogging. I turn it off, start it put it in drive and it takes off fine , then again a little later same thing, ac stops cooling and no speed pick up. I'm clueless. :/

    How can your engine rev up and you don't gain speed? It sounds like your electrical system is surging. Could be a bad battery. Could be a bad wire on your alternator. Could be overtightened bolts on your PCM wire harenesses. I would start with the battery and alt. The alts are weak in these cars, and the wire that tells it to turn on is fragile. Buy the lifetime replacement alt if you have to replace. If the wire is bad, you can disassemble the plug and rewire it easily. Prob gonna break it if/when you pull the alt. I did. Twice.

    It looks like in the video your speedometer is dead too.
    I'm asumming that was a driving video.

    I would check the ac compressor to start with. Does it spin freely?

    I undertstand. I will try to get a scanner and look at the codes that you have beside the emissions. Clear them all and run the car again. then check codes again. Does it happens with the A/C off as well?

    Umm you also have no oil pressure.

    Car sounds like crap. Scan codes if possible, but check your oil 1st.

    whens the last time you filled up prior to the one you posted?


    Also your battery gauge show you way low. Should be around 13.5 the lowest, as high as 15.

    very good point about the oil pressure... has your car been leaking oil?

    If i recall correctly i had a friend that had something similar but not on an F body and it turned out to be a PCM.

    battery is new. just bought it a week ago. car has actually been sitting on my driveway for a month, just got it out from a wreck about 3 months ago. didn't drive it for about 3 months. all i have installed on it performance wise was a tranny cooler, new radiator, and battery.

    you might have shorted out a harness. go back over it again.


    I had shorted out my wire harness in my column in an old truck I used to have while installing a radio. Gauges worked fine until I turned the lights on, killed all of the gauges and truck ran like crap.

    the only other thing that i know it causes the car to shut off is the crankshaft sensor but not like yours. I will throw a code if it was bad anyway.
