I just cant figure why my engine wont shut off after unpluging my MAF. What could be wrong?

OK im take a stap at this. First what engine? Second what is your main problem imma guess your car doesnt turn off? is it the engine or the electrical? your car shouldnt turn off by unplugging the maf it should just idle funny or just no be able to go thru the rpm range since it cannot acomidate for the air fule ratio. If your having problems turning it off and you turn the key and all take it out it either the lock cylinder, ignition switch, or stuck relay. thats what i think let us know a little more information and how this happened, or what occured. was it running fine one day then poof nothing, or are you doing a n engine swap and this is a problem thats occuring. Also Check to see if your wires are cut, someone on another forum had rubbed thru the wire harness and had the same problem.

I got a black top sr20det which drives fine and all. Until I decided to up-grade my maf to a n62/nistune ecu chip(un-tune). Even with the stock ecu/maf it still wont cut off or idle funny after I take off the maf or after revving the engine up beyond 3500rpm.
Also with the n62/nistune ecu I cant adjust my idle to be below 1200rpm. And its running rich at idle.
