Get a spray can of throttle body cleaner.Take the big hose off coming from the air cleaner to the throttle body.Get someone to press the gas petal or do it yourself under the hood.Look inside the throttle body and you will see the flap opening and closing.Spray the cleaner on the flap and inside the throttle body and clean out all of the black stuff .Do not use carburetor cleaner it will damage the throttle body.It is best to replace a drive axle with a rebuilt one when the boots are busted.Trade yours in for a rebuilt axle this will fix all of your problems.

    This is likely a problem with the Mass Airflow sensor, it is a sensor that reads the amount of air going into the engine, when it fails it causes severs hesitation and power loss. Contact a local parts store or your GM dealer for a rebuilt one, the part is about $150.00. It is locate in the air intake hose to the engine.

    Replace first, the fuel filter if this has not already been done. You may have a plugged filter, and these are very inexpensive. If this does not resolve the issue, locate the MAS (mass airflow sensor) located between the throttle body and the air filter housing. Start the car and let it idle normally; with a screwdriver handle or other such small tool, tap the mass airflow sensor (small black unit; will have a wiring harness hooked to the side of it); if the car dies, stalls, hesitates; first purchase MAS cleaner at the local auto parts dealer - specifically ask for Mass Airlflow Sensor Cleaner. It will should cost between 7-12 bucks - but you wont need the whole can - however, when using it: (if the car does not die, stall or hesitate and the idle stays the same, than the sensor is not bad) If it does however:
    1. Remove the MAS (disconnect wiring harness) you may need to pull the top end of the air filter housing off.
    2. Spray inside the sensor generously from both ends ensuring it's entirety is sprayed. Let stand for 15 minutes to airdry.
    3. Re-install the sensor and start car. If there is still no improvement and the car hesistates, 1. Ensure the air filter as well is in good repair, and that there is nothing causing any air flow restriction between the airfilter and the throttle body.
    4. If the airfilter is good, and there are no restrictions to air flow, consider replacing the MAS, however if you can get the car to the auto parts dealer, or to a technician (who may charge; auto parts dealers usually don't) have them run a diagnostics test on the car.
    5. At this point, if cleaning the sensor has made no improvement, and the car stays idling, does not hesitate when tapping the sensor, the air filter is good, the fuel filter is good - then the next step is to replace the fuel pump.
    Please let me know if you need further assistance.

    Hello. I can assist you. Generally when a scan is done, the technician will clear out all of the codes and hope that the problem self corrects. I am glad you passed the state emissions test. Now let's get to the bottom of the hesitation. Generally all lincoln and ford cars that hesitate like yours have a problem with the "mass airflow sensor". Most likely you will need to replace it.
    The Air Flow Sensor or Mass Airflow Sensor (MAF) is one of the components of an electronic fuel injection system and is found in many of modern vehicles. The Mass Air Flow sensor is usually installed inside the intake air duct between the air filter and the engine. The Mass Air Flow sensor is used to measure the amount of air entering the engine. This measurement is used by the engine computer or ECM to calculate proper amount of fuel injected into the cylinders in order to provide optimum combustion and low emissions.
    Problems with Mass Air Flow sensors are common. Bad or contaminated Mass Air Flow sensor can possibly cause a wide range of various vehicle driveability problems such as stalling, especially when the engine is cold, misfiring, poor acceleration, etc.
    In addition, a problem with the Mass Air Flow sensor often causes the "check engine" or "service engine soon" light in the vehicle instrument panel to illuminate.
    The "check engine" or "service engine soon" light comes on when the engine computer detects some fault in one of the components of the emission control system.

    Mass air meter not reading vane postion


    hey rob_andersen,

    yes their is a way to replace the mass air flow. Get a can of brake clean or throttle cleaner, throttle cleaner is going to work best. remove the until and spray it down with throttle clean, let it dry for about 15 min. and reinstall it.

    Now a little warning for you, IF their is no visual damage to the mass air flow then you can do this successfully. Now the reason why I always replace them instead of spraying them down is because is MOST cases the mass air flow will start acting up again. Sometimes it takes a weeks, sometimes months, sometimes years its hard to say.

    But the worst you have to loose, is it doenst work an your out 5 bucks for the can of fluid.
