I cleaned out my maf and iat with electronic safe cleaner the other day, once i put everything back together it threw both codes for them. I checked the wiring on the maf and it read 1.3v at idle and 2.4v max. I unpluged the maf and tried going past 2.5k and it wouldnt so I'm very confused right now.

When you pull the maf, it won't rev past 2500. That's normal. With the connections for the mafs, I'd check them over again to make sure they're snug. Is the car idling weird or driving funny?

When you pull the MAF and The IAT the computer knows it unless you disconnect the battery. Just re-install everything on your car to normal and then clear the codes on your computer and you should be fine.

The car is idling fine, some hesitation but i think thats caused by my knock sensor and something in the fuel injection system (threw both codes for them). But as far as the maf and IAT, its pretty normal. I havent been able to pull 4.0v from the maf at 4000 rpm
