Question about 1991 Lincoln Mark VII

1 Answer

I have a 1991 Lincoln Mark 7 LSC 5.0, I asked about this car about a month ago and recently learned that it is not an Intake back fire, reading the manual further I discovered the problem goes deeper,

The noise developed when I got the engine just into the 5,000 RPM on the tach, but I babied the car another 30 miles to the house. One local mechanic says that I will need a new engine and a crate motor costs 4 to 5,000 but he has a 351 with 60,000 miles on it, which is what my engine had also, for $ 600.00. Can you help me with anything, Please Terry.

SOURCE: 1991 Lincoln Mark VII LSC spark plugs and wires

A pair of decent long handled pliers/plug boot remover are recommended. apart from that, maybe some swivel pieces for the plug socket to get at funny angles.

recommend you:
- buy decent wires & plugs.

-put a dab of silicone on every wire boot to ensure easy fitting.

-Be verycareful when tightening the plugs so as not to crook the socket and crack the porcelain on the plug.

-Plugs should have a dab of copper grease or similar on the threads

-Plugs do not nee to be super tight, they have a compression washer at the base of the threads or a tapered thread fit that seals them well. only tighten them with a short length 3/8 ratchet not a big 1/2 inch - you'll strip the thread and regret that forever.

-Always make sure the wires dont touch the exhaust manifold and make them look like you just bought the vehicle, nice and straight and in tidy rows. You'll need a flat screwdriver, short, to undo enclosed plug wire harness mountings. be patient, they do unfasten ok once you suss em out.

-plugs are usually already correctly gapped. check them. gap can be check with Autozone or where u get the plugs from.Note the gap may be brand dependant - bosch platinum take a different gap to cheapo champions....

Hope you get a good job done
:)

you don't have to worry about a special tool if you are replacing the wires but you will need a 5/8 socket with a rubber boot and an extension and maybe a swival to remove the plugs if there is an auto zone near by they will print you out a diagram for free

SOURCE: My 1991 MRK 7 LSC 5.0 just devloped an intake back fire and the manual I have isn't giving me specific info for exhaust or intake for either

Based on your description I would say one of the intake valves stuck open. If that is true, you will likely have to remove the head to fix it.

Some engines had a part called an idle control solenoid. This was a part that controlled the air flow at idle. A loose crankshaft sensor could also do this. Then when you have extreme signals from the O2 sensors, the engine will float from lean to rich and back again.

I have a 1992 Lincoln Mark vii lsc. Fuel pump problem!


This sounds like the PCM has taken a turn for the worst. The pcm relay sends power to the fuel relay for 2 seconds to prime the fuel system just before start up.
Then the pcm ungrouds the signal for a prove out.
