I connected the original maf and it still runs the same, so I unplugged it while the car was idling and it didn't change how it ran so it has to be a bad maf. Its possible that the one off eBay is a dud right? I mean I spent like 30$ on it so I'll take the bite out of my wallet and buy a boshe if need be. So I don't need to have a computer reset my computer in my car or anything, (when I get a new one) it should just be plug and play correct?
