Another Code 33 Question

Ok, once again, 87 Iroc 305 TPI. I'm getting a code 33 so I know it's the maf circuit. If I start the car and run it then unplug the maf I get no change.
What is this telling me?
Thanks

Re: Another Code 33 Question

Re: Another Code 33 Question

Check the MAF relay, and the MAF burn off relay, along with all vacuum lines and the throttle body shaft for leaks.
