So I'm at my wits end, I have been working on this same code for two weeks now its: P0101 Mass airflow performance. I tried cleaning the sensor with maf cleaner, replaced the air filter, made sure all the clamps were tight then went and drove some miles to check for codes. The light came on around 55 miles, so since I didn't see any boost leaks or any other issues, I assumed I needed to replace it, I bought a new sensor and drove about 100 miles and no light.. Good news right? Well when I pulled it in to the smog station (thanks to living in commefornia) the light came back on 😠. I don't know what else to do.. Does anyone have suggestions for where to look or what to test?
