1991 Lincoln Mark VII, runs good then tackometer starts going nuts and the engine stalls out

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

Check the timing but FIRST disconnect the SPOUT connector. reset the timing and check your firing order. It's listed on the emissions sticker on the fan shroud.

Technically it will fit, if you dont like having a hood. But again. Stick with the trusty 302, Toss a Novi 1000 on it, and enjoy.
