P0102 = MAF sensor reading too low. Steps: 1) Unplug MAF sensor and start engine — if runs better unplugged, sensor is bad. 2) Clean MAF sensor with MAF cleaner spray. 3) Check for air leaks after the MAF sensor (intake tract). 4) Check wiring connector for corrosion. 5) Replace MAF sensor if cleaning fails. MAF sensors: $30-150. Do NOT clean with carb cleaner — damages the sensing element. Use only dedicated MAF cleaner.
