    Dude, what you called the MAP sensor, is where the PCV valve is.Push down and turn counterclockwise, pull up, and there's your pcv valve.

    Not a sensor problem remove the map sensor and look if the pcv valve is missing or the o ring around the valve is missimg

    Why does mine always run rough / stall for 3 or 4 miles after topping off gas tank ?

      Unsure. But some things that can be done if you haven't done it.
      Clean the MAF sensor if equipped, tune up, change out the PCV , check any pending fault codes, O2 sensor faulty and maybe check for vaccum leaks. More undetected air is entering in and the Computer is adding fuel to make up for the extra air entering in after the MAF sensor.
      Hope that helps?

    I wanted to buy one of these but I think it's just best for me to buy a Toyota around the same year or honda so I won't have these little issues here and there.
