you got the code because you un plugged the maf and ran the car, thats normal. if you clear the code, or un hook the battery for 30 minutes that will also clear the code. plug the maf back in and the code should not set for the maf again.

if it ran the same with out the maf as when its plugged in, thats not your problem.

you may want to cancel the maf order you placed.
