It sounds like a door ajar switch is broken. The door switches are located in the door on the latch mechanism. To get to it you will need to remove the door trim panel to gain access to the door latch.

The switch is available for around $20 - autozone part number SW1979 or SW3688

two of the bolt holes are close together allowing it to go back one way.

Hi hope I can help.
1.Fist change the spark plug. this is the main cause of most misfires,
2.If that don't work switch your coils. (remove one of your other coils and switch it with the #3 coil. If the misfire moves to the other cylinder then you know you have a bad coil and it need to be replaced.
3.preform a compression test.
4 Also check your fuel pressure.
Hope this helps
Please leave feed back

Your best bet, is to pay the big bucks
for the Ford Wiring Diagrams and the

You can't expect people to tell you

4.6L Engine - replacing thermostat



CAUTION Never remove the radiator cap under any conditions while the engine is running, or while hot. Failure to heed this caution could result in cooling system damage or severe personal injury.
  1. Drain the engine cooling system until the coolant level is below the thermostat.
  2. Detach the lower radiator hose, the return hose and the degas bottle hose from the thermostat housing.
  3. Remove the two mounting bolts, then remove the thermostat housing.
  4. Remove the O-ring and thermostat from the housing. Discard the O-ring.

To install:

NOTE To prevent installing the thermostat with an incorrect orientation, the housing contains a positioning slot. Install the thermostat so that the bridge part protrudes into the housing, not into the intake manifold.
  1. Position the thermostat and a new O-ring on the housing, then install the housing.
  2. Install the two mounting bolts, and alternately tighten them to:
    1. 4.6L SOHC engines 15-22 ft. lbs. (20-30 Nm).
    2. 4.6L DOHC engines 89 inch lbs. (10 Nm).

  3. Connect the lower radiator hose, the return hose and the degas bottle hose to the housing.
  4. Fill the cooling system, then start the engine and check for leaks.
  5. If necessary, top off the cooling system overflow reservoir.

  1. Drain the engine cooling system.
  2. Remove the air cleaner outlet pipe.
  3. Remove the 2 thermostat housing bolts and separate the lower and upper thermostat housings.
    1. Discard the thermostat O-ring seal and remove the thermostat.


To install:

NOTE Lubricate the O-ring seal with clean engine coolant.
  1. Install a new thermostat with the smaller plate facing upward and the O-ring seal.
  2. Position the lower and upper thermostat housings together and install the 2 bolts. Tighten to 89 inch lbs. (10 Nm).
  3. Install the air cleaner outlet pipe.
  4. Fill and bleed the cooling system.

fuel pumps only run for a few seconds when the key is first turned on, then runs all the time after car starts, need to check fuel pressure at the fuel rail, or could be electrical, also check the fuel pump safety switch the owners manual should tell you where it is located

If the fluid is leaking out than you will ruin the pump by driving the vehicle.

You will need to get your computer in your car scanned with a (On-Board Diagnostic) OBD II Scanner in order to determine what Trouble Code is stored in your computer. Most AutoZone or O'Reilly Auto Parts stores will do this for you at no charge, retrieving the code will put you in the right direction to solving the problem.

the engine is misfiring under a load, the most common cause is a bad spark plug , bad spark plug wire or a bad ignition coil. in any case a good old fashioned tune up should take care of it......HAVE FUN
