How do I change the fuel injectors in my 1994 ford Thunderbird lx v8

SOURCE: what is the firing order for a 1994 ford thunderbird?

Firing order 1-4-2-5-3-6 ------- front | 1 2 3 | of | | vehicle | 4 5 6 | ------- Distributor rotates counter clockwise

SOURCE: engine code p0307 cylinder #7 misfire

It could be carbon deposits on valve seats keeping valves from totally closing. You can try getting you a can of motorcraft PM3 top end engine cleaner and get engine up to operating temp then remove one of the small vacuum lines from the intake and draw the contents of the can slowly into the engine.After you have drawn in the contents shut engine off and let it soak for about 45 minutes then crank it back up and let it run until it clears. Now it will smoke like a forrest fire while you are doing this so don't be alarmed,just tell the neighbors you are spraying for mosqitos.This may cure the problem. If not you may be looking at a valve job.
This can be verified with a compression test if this is what is causing it.

Sounds like a weak battery

Testimonial: "A good point. The battery has been tested and appears to be ok."

Disconnect the battery & any fuel lines you can and the same with electrical connectors first of all. Drain the tankwith a siphon pump if 3 gallons or more of fuel is present. It gets heavy to replace back in and dangerous too.. Have the tank supported now & remove the bolts from the tanks mounting straps. Drop the tank down about 6 inches and check for other connection that need to be removed
RFemove the center retainer to remove the fuel pump with the sending unit
I would replace both items since it is an older car and also replace the filter sock to the pump too
Reverse this procedure to install

SOURCE: 1994 Ford Thunderbird 4.6/V8- diagnostic codes:

Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.

Note: This DTC is very similar to P0174, and in fact your vehicle may show both codes at the same time.
Symptoms

You will more than likely not notice any drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration.

A code P0171 may mean that one or more of the following has happened:

• The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
• There could be a vacuum leak downstream of the MAF sensor.

Possible solutions include:

• In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
• Inspect all vacuum and PCV hoses, replace if necessary
• Check for a dirty fuel filter
