Yes a faulty air flow meter can have an effect on your engine sometimes they can be cleaned with an electrical cleaner and an airline but make sure your air filter is clean first as they can also alter engine performance making many people think that the air flow meter is at fault

SOURCE: running lean at idle & rough idle stalling.

Replace the fuel filter,have the fuel pressure check,it is most likely the fuel pump.

SOURCE: low/poor idle

Here is what you need to do, a cleaning of the intake throttle blade and the idle speed control air-bypass valve, they get full of gunk over the miles and cause idle issues (stalls) like yours,
Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

SOURCE: Air flow meter

Air sensor for 99 Protege 1.6L, might be applicable to your car as well.

There are two screws on top of the sensor, which should be located past the filter on the air intake. Remove the screws carfeully and pull the sensor out. If you look through the sensor, there should be a tiny element, use throttle body cleaner to blast any deposits off the element, and clean other parts of the sensor while your at it. Just be careful and don't physically contact the element.

The cars computer detects the amount of energy required to heat that element up to a certain temperature, and relates that power requirement to the amount of air flowing by (air temperature and pressure is also measured by the computer). When the element gets dirty, it becomes insulated and the calculations are affected, which will cause the car to hesitate on acceleration. Fuel economy is also affected.

You might hear from people that this part can't be cleaned, I've been doing it for the last 4 years and it is the best 'tune up' you can do for the car, it will run like new!

SOURCE: check engine light low air flow

I assume you mean EGR low flow P0401. This is ging to be a faulty EGR dpfe sensor or the ports i nthe intake are clogged behind the EGR valve.

06 f250 5.4 code r107


Do you mean p0107 ? If so that is P0107 Ford - Manifold Absolute Pressure/Barometric Pressure Sensor Low Input

Possible causes
- Faulty Manifold Absolute Pressure sensor
- Manifold Absolute Pressure harness is open or shorted
- Manifold Absolute Pressure sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM) help.jpg What does this mean?
When is the code detected?
The ECM has detected a performance fault with the MAP sensor
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine rough idle
- Engine hesitation
P0107 Ford Description
The Manifold Absolute Pressure (MAP) sensor provides instantaneous manifold pressure information to the engine's Engine Control Module (ECM). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow (MAF) sensor to detect the intake airflow.

My 95 toyota tacoma, hesitates during acceleration around 2500 then takes off strong, it a 5 speed


You should know that while those problems can be caused by several issues, including low quality or altered fuel or even a loosely tighten fuel cap, the most common cause is a dirty MAF flow meter sensor.
The MAF sensor (Mass Air Flow Meter Sensor) is in charge of detecting how much air (in mass, not volume) is coming in to the engine, so the ecm computer can calculate the amount of fuel to be injected.
Some times this sensor gets contaminated by lots of microscopic debris that scape the air filter and accumulate on its sensing parts over time. The resulting effect is that the MAF flow meter sensor gets less "sensible" and detects less air than it is currently entering the engine. The reaction of the ecm computer will be to inject less fuel to keep the air fuel balance, taking as reference the false reading of the MAF flow meter sensor. This will produce a too-lean mixture, which is responsible of the hesitation, the loss in power and the check engine light.
If your car engine, besides the hesitation, is also producing knocking or engine pinging at high loads, like when going up through a hill, it is attributed to this too-lean condition.
Before going to an auto parts store or to a mechanic to fix the problem, you should try fixing it your self. If the problem is a dirty MAF flow meter sensor, the solution is to clean it, plain and simple. That may save you some money that a mechanic will charge for cleaning it (you could do the same) or for replacing the part when most of the times it is not damaged, just dirty or contaminated.

My car has code PO171 WHAT DOES IT MEAN?


This means your engine is running too lean on the fuel-air ratio. Get this fixed as it can damage the engine after a while.

Possible causes are



• Air intake leak (hose loose)
• Fuel line pressure low
• Injector blockage
• Heated oxygen sensor malfunction
• Mass air flow meter fault
• Engine coolant temp. sensor failed

The most likely cause is the oxygen sensor

No power jucking but can drive throw it is it the air mass meter !!!!


Your description, I venture has a number of things misspelle by accident. "Jucking" Maybe "Jerking?" But you can drive "throw" as though" it is the air mass meter.
Keep in mind, I am not making fun of you, I have made my share of misspelled words and sentances which were a little confusing.
As for the mass air flow sensor, looking at technical service bulletins, there is one which pertains to the throttle position sensor, Air Idle Contril Valve and the Mass Air Flow Meter. They reference connections which need to be checked and insured that they are clean. These can cause a balk or hesitation and stumble. False air problems can also caise the same conditions. Look for vacuum leaks. The main hose which connects the air mass meter to the throttle body may have a crack or tear in it. As you apply throttle, the engine is going the jump and shift position a little. This can cause a small to massive air leak between the air mass sensor and the throttle body. Un metered air means poor performance.

replace your fuel filter first. If that does not do it, then try an air-flow meter. (if the check engine light is on it may be an airflow meter.

Low miles per gallon


Hi the first thing you might want to look at is low tyre pressures or a fuel leak? After eliminating those i would look at the MAF or mass air flow meter. If you unplug your air flow meter with a hot engine and drive it there should be a large difference in performance, if there isnt then replace the MAF as it is faulty.
