    Same thing happen to me and found a bad AFM. Check my signature on AFM rebuilds. You should read approx. 1.5-4.5 volts DC while the car is running. Use the pin seconds from the left side of the connector. Must be plugged in while performing test. 1 volts DC at idle speed, 4.5 volts DC at full throttle. (air sucking in faster opens flap.)

    Multimeters are very limited as tool for this test because they acquire signal relatively slowly. Ideally you want an oscilliscope. But if your AFM is really bad, you will find non linear or near zero volts even when the flap is opened.

      Greg, thanks for the insight:)

      I have access to a spare parts car for low costs.
      I'm picking up:

      o2 sensor
      CPS
      AFM
      fuel pump
      fuel rail+injectors
      FPR
      FP relay

      all for about 80-100 bones.

      I'll replace one at a time untill this hoooor runs right again.

      I'll start from the back, as I do suspect a fuel issue...

      I removed my fuel level sender, and there was what looked like marguard/por-15 on it...
      once I replace my fuel filter, I see what color the gas is...i'm really hoping it's just a simple pump replacement.

      either way, I'll have spares to boot.

      can't go from running flawlessly to like shit just like that.

        Ffs.

        Replaced fuel filter
        Fuel pump
        Maf
        coil
        Fuel pump relay
        Main relay

        Still nothing

        Turns over like a champ, kind of catches, give it gas, wants to catch even more but dies.

        Really gave it gas, sounded like it ran on 3 cyl than died.

        What else???????

          Fixed.

          Apparently you need fuel in a fuel tank in order to have the engine function.

          Wow.
