Top 10 1997 Ford Expedition Questions & Answers

It is a common problem, you will have to change bank 1, o2 sensor as it is covered in burnt oil and fuel telling the computer to run lean.
hope this help

Your valve-cover gaskets have failed. A clogged PCV valve may have caused the leak or made it worse.

The mechanic will likely replace them for about two hundred bucks.

Good luck.

first, you need to read the Lamp Fault Code, LFC from the flashing light. Here's how:

Lamp Fault Codes
When the restraints control module (RCM) detects a system fault, it will cause the air bag indicator to flash a coded sequence: a lamp fault code (LFC). The code is two digits. The first digit is flashed with a 0.5 second interval between pulses. There is a 2 second pause before the second digit is flashed, which also has a 0.5 second interval between pulses. There is a 5 second pause between each display of an LFC.
Each LFC is flashed five times after which the air bag indictor will remain lit for the remainder of the key-on cycle. If there are multiple LFCs, each LFC will flash in order of priority.
-------------------------------------------------------
The fault could be in the air bag circuits, the canopy circuits, the pretensioner circuit on the seat belts, etc.
Report back with code.

here's some of system.

SECTION 501-20B: Supplemental Restraint System 2003 Expedition/Navigator Workshop Manual
DESCRIPTION AND OPERATION Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) The air bag supplemental restraint system (SRS) is designed to provide increased collision protection for front seat and second row outboard occupants in addition to that provided by the three-point safety belt system. Safety belt use is necessary to obtain the best occupant protection and to receive the full advantage of the SRS.
This vehicle line contains dual stage deployment (advanced restraint system) driver and front passenger air bag modules. These vehicles can also be equipped with optional safety canopies that deploy from the A-pillar to the C-pillar upon a side impact or if a rollover condition is detected. If equipped with safety canopies, a unique restraints control module (RCM) is used.
See the following illustration for deployable component location.

ball joints won't squeak like that; they make a popping noise when they're bad. it is very common for shocks to get water in them and start squeaking, and it's usually a horrible screeching squeak. The only way to get rid of the squeak is to change out the shocks. Hope this helped.

STARTER - REMOVAL & INSTALLATION
4.2L, 4.6L, 5.4L and 6.8L Engines


Fig. 1 Remove the starter terminal cover


Fig. 2 Remove the cables from the starter terminals


Fig. 3 If equipped, remove the ground cable retaining nut from the stud and remove the ground cable


Fig. 4 Remove the two starter retaining bolts-4.2L engine shown


Fig. 5 Remove the two starter retaining bolts-4.6L engine shown, 5.4L and 6.8L engines similar

1. Disconnect the negative battery cable.
2. Raise and safely support the vehicle.
3. Remove the starter terminal cover.
4. Remove the terminal nut and separate the battery starter cable from the starter motor.
5. Disconnect the solenoid S terminal connector, if equipped with a starter mounted solenoid.

To disconnect the hard-shell connector from the solenoid S terminal, grasp the plastic shell and pull off; do not pull on the wire. Pull straight off to prevent damage to the connector and S terminal.

1. Remove the starter motor retaining bolts.
2. Remove the starter motor from the vehicle.

To install:

1. Place the starter motor in position and install the starter motor retaining bolts. Tighten the bolts to 15-20 ft. lbs. (20-27 Nm).
2. Install the battery starter cable and a terminal nut to the starter motor. Tighten the terminal nuts to 79 inch lbs. (9 Nm).
3. Connect the solenoid S terminal connector, if equipped with a starter mounted solenoid.
4. Install the starter solenoid safety cap, if equipped.
5. Lower the vehicle.
6. Connect the negative battery cable.
7. Start the engine several times to check starter motor operation.

I hope thats helped (remember rated this).

Hello Projocs03,

Tires are typically measured tire width (sidewall)/tire ride height/wheel size. The differences of the two tire sizes you published are .4 of an inch difference in width/sidewall. And about .55 in over all diameter which would impact you revs per rotation. Depending on your wheel size.

Attached is a comparison of the two given the variable of 17" rim.

I added the above link so you can research further or change any variables you need to know. However, the most important thing to understand is the impact of your speedometer. Different sizes will have different impacts. For example going to a bigger tire will show a slower speed on your spedo that your traveling.

Good luck

To my knowledge the MAF relay is mounted in the engine compartment area (As you say under the hood) the two relays there are identical if I stand to correction.With the engine switched off (never ever remove a MAF relay or plug and then try to start the engine, or even merely switch on the ignition as this will throw the computer out after which the engine will never start properly again and you will have to go through a major process to reset the computer.) remove the relays and check the plug in connections underneath they are usually situated a bit differently compared to each other, this should give you an idea which one is the MAF.

Code P1451 is a EVAP control system canister vent solenoid circuit malfunction. If you're lucky it's just a bad gas cap but chances are the solenoid is bad or the wires leading to it are damaged or broken (more likely). Check the attached diagram for the canister location and have a look. If it's just damaged wires you can soldier a new wire splice in place and shrink tube it for protection. Make sure it's not going to rub against any metal that will damage it again.
