Try cleaning the MAF and changing the air filter before looking at the po175 code... P0101 CHEVROLET - Mass Air Flow Sensor Performance...Possible causes; Faulty mass air flow sensor, Intake air leaks, Dirty mass air flow sensor, Dirty mass air filter, Mass air flow sensor harness is open or shorted, Mass air flow sensor circuit poor electrical connection...Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.......P0175 CHEVROLET - Fuel Trim System Rich Bank 2...Possible causes; Faulty front heated oxygen sensor, Ignition misfiring, Faulty fuel injectors, Exhaust gas leaks, Incorrect fuel pressure, Faulty Mass Air Flow (MAF) sensor.
