- Scanned for codes and found P0171 system too lean bank1. P0174 system too lean bank 2. Current data is within vehicle specifications. Checked connection where customer supplied cold air intake, everything is in place. Saw where mass airflow sensor bolt had been broken off sensor however the other bolt is holding it tight to pipe. Sprayed sensor area with cleaner to see if fuel trims would change and they did not. Test drove vehicle approximately 8 miles after clearing codes and was able to set all readiness monitors except evap, no issues found at this time.
