    Ford is the only sincere manufacturer I know that will confess that a model of their cars' engine is complicated.

    Can you take to my advice?

    Drive to Ford garage and have their mechanic fix the car for you.

    Best bet for you in this situation.

    Cheers and remember to rate this discuss.

The MAF (Mass Airflow) only affects fuel delivery to all the injectors, it can't affect fuel delivery to just 2 of them, have you run the trouble code tests, have you pulled the injectors out and confirmed they are inop? are they clicking? the Powertrain Control Module can cause this problem, but very rarely is that the problem.

    is there 12 volts to one wire of the 2 dead in injector connectors with the key on? have they been electronically flow tested by a Ford dealer? do u have a test tool called a NOID injector pulse tester? if not get one, it shows whether the injectors are getting a pulse signal from the computer, they are avil at any good auto parts store.

Have p0171 code


A code P0171 may mean that one or more of the following has happened: The MAF (Mass Air Flow) Sensor is dirty or faulty Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry. There could be a vacuum leak downstream of the MAF sensor Possible cracked vacuum or PCV line/connection Faulty or stuck open PCV valve Failed or faulty oxygen sensor (bank 1, sensor 1) Sticking/plugged or failed fuel injector Low fuel pressure (possible plugged/dirty fuel filter!) Exhaust leak between engine and first oxygen sensor

Engine light on. Scanner shows code P0172. What is the problem?


Overly rich fuel ratio, this is usually an issue with a leaking injector or unusually high fuel pressure which can be caused by a damaged fuel regulator.

What do p0171 code mean


Fuel system - Bank 1 lean.

This is usually due to a dirty MAF sensor heated wires. Remove MAF Sensor and spray the tiny heated wires with carb cleaner or MAF sesnor cleaner. ALso, look for air leaks in the air intake system that is allowing unmtered air to bypass the MAF sensor.
Your oxygen sensor is eprting that not enough fuel is going through the injectors. Look for splits in the convolutes of the big air intake hose. Also, the PCV valve could be bad
My guses is there is an air leak.

Multiple cylinder misfire, codes P0354, P0356, P0357, P0361


clean the MAF, Mas Air Flow Sensor in the air intake tube first. Use carb cleaner or MAF cleaner. Do not touch the 2 sensor wires that you spray. delicate!!

ALso, put a bottle of Chevron Techron Fuel injector cleaner in the fuel tank, 1/4 tank or less.

Try that first. Also, replace spark plugs, put antiseize on the threads. Last resort is to replace the COPS, Coil on plug for each offending cylinder.

Misfire Definition: A misfiring cylinder is lacking power relative to the other cylinders. The causes for a cylinder specific misfire could be fuel, spark, or mechanical problems. Perform a thorough visual inspection. If no visible concerns are found use the following WDS tools for misfire diagnosis:
  • Self-test (Check for codes first)
  • Power Balance (Identify the cylinder of concern)
  • Relative Compression (Rule out a possible mechanical issue)
  • Fuel (Make sure fuel injectors are not restricted) (plugged)
  • Ignition (Make sure spark plugs and coils are working properly)
  • Oscilloscope (Detailed signal analysis)

2001 ford focus had the spark plugs and wire change. Has a code po171.. ran good for two days. The spark plugs are blacker than acs of spades which is running rich. Don't know what to do next. To me its...


PO171-System to Lean (Bank 1)

Air filter cover tight?
All intake ducting tight?
Clean MAF Sensor.--CRC MAF Cleaner
Fuel Pressure Regulator?
EVAP Purge Valve-stuck open?
Vacuum leaks?
EGR System-issues?

Seems your getting a lean O2 Code,because it is trying to correct for a rich condition,as you said.

Is the Throttle Position Sensor-original?

Work on what is driving it rich,my list is a possible.
