My cars check engine light popped up recently, when I scanned to see what the problem was it gave me P0101 code (MAF sensor). So, I cleaned the MAF sensor, got a new air filter, and reset the computer, the light came up again so I bought a new MAF sensor and reset the computer again. The light still came up again so I checked the PCV valve and it was good, and next I was planning to clean the throttle valve, but the only problem is that I don't know if I will need to reprogram the computer after I clean the throttle valve, if so, how do I reprogram it or where do I take it to reprogram?
