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?

I would suggest MAF, as I just seen this on a car last night...

Your in the FL area so you have afew people you can get a working MAF off of either be for testing or replacement

I was with jbuhrman last night when this happened to one of the socal3s members and I knew what it was instantly because my maf was bad and did this same symptom prior.

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.

This is true, I overlooked that.

Correct I have seen this multiple times, it does not always throw a CEL.

No there's no IC pipes off, that I know of...As I am putting this thing together and nearing completion of this big project I keep running into more and more problems. I think I need a new platform.

Happened to me with massive vac leaks. Find vac leaks first!
