I stopped by AutoZone today and they plugged in to my car and the code read P0101 Mass Air Flow Sensor, check range performance. Does this mean I need another new one? This will make 4. Also on the way home my car wouldn't shift into 4th gear on the highway. So I was stuck going 60 (not a biggie), but at 32-3400 rpm. This is very different than the last 2 issues with the MAF. Can anyone help with troubleshoot this one??
