P0171 is set when fuel trim is driven rich beyond a certain value. Possible causes are:

? Air induction system malfunction.
? Fuel injector restricted.
? Defective Mass Airflow (MAF) meter.
? Defective Engine Coolant Temperature (ECT) sensor.
? Improper fuel pressure.
? Exhaust system leak.
? Heated oxygen sensor No. 1 circuit is open or shorted.

Check your fuel pressure first and vacuum lines off or cut/damaged. First
