Question about 1998 Lincoln Navigator

1 Answer

Hesitation or jerking at various speeds when accelerating in 2001 Lincoln Navigator

2001 Lincoln Navi, theft light illuminates (flickers) when accelerating and I feel what seems to be a slipping of the transmission usually at normal road speeds and at highway speeds as well. It feels like a bumping and passengers can feel it too.The tranny fluid is in good condition and quantity is right where it should be. If this is a coil pack, how do I find out which one is bad? Also since they are so far down inside how do I access them to change them?

Cutting out when accelerating have noticed the "theft" light blinks when this happens.

That is your anti theft system cutting in. In most cases this happens when you have a vehicle that uses a security chip in the ignition key or the alarm itself malfunctions when it is built into the PCM of the vehicle. Unfortunately your best chance to test for this is the dealer.

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.
