    Bad MAF?

    My car will not run with it plugged in but as soon as you unplug it, she idles perfectly fine a little rich but fine. Do I have a mad MAF or am I missing something?

    In my experience this does mean the MAF is bad.

    If your MAF is bad it should throw a CEL. When you say it doesn;t run does it not start or does it idle out?

    Alright thanks, my CEL is on but it's normally on since I have no cats and such. I also can't find where to plug in one of my o2 sensors so that would also throw a CEL but thanks everybody I will switch it out and see how it goes.

    You also get the same symptoms (bad maf reading) when you blow an IC pipe... Have you checked for leaks?

    Not necessarily. My MAF went bad but didn't throw a CEL.
