The front park plugs are easy to replace. For the rear plugs, there are two different ways to do it.
1. Get under the vehicle. There is room to get your arm up there with a small extension.
2. From under the hood, remove the plastic panel at the base of the windshield. Get a universal flex spark plug socket and an extension. Then you can get to them. Still is difficult, but it can be done.

there are many different circuits in vehicles now days. It is very possible that you may have full voltage at some circuits and not the correct voltage at others. A relay clicking may be caused by not enough voltage to hold the relay down or that the module that controls the relay may not have enough voltage to know what it is doing.

you should go through and check for a voltage loss somewhere in the system. A switch, a connection, a bad fuse panel. there are all sorts of electrical things you would need to check. I would start at the wiring that goes to you ignition switch. Check to see if you have the correct voltage coming from the battery source for voltage to start and run your car.

1997 Mercury Sable - Easy to Replace Spark Plugs and Wires?

Unread post by searchlight » Thu Oct 15, 2015 3:22 pm

I have a 1997 Sable that is due for spark plug replacement and wires. Mileage is 99,323. I think definitely because sometimes the engine shakes for a few seconds when I start the car, and then smoothes out. I have already replaced the PCV, the IAC Valve, and have cleaned the intake manifold, and MAF sensor. The car has the 3.0V6 Vulcan.

The three spark plugs in the front are easily accessible but the three in the rear look difficult. I have a spark plug socket, ratchet, and ratchet extension. Would I be able to replace these and the wires, myself easily, or should I pay $200 for a professional to do the work?

Do you also recommend Anti-Seize gel and Dielectric Grease? Thanks.

Btw, I have read in other forums that many people say that the 3.0V6 Vulcan is a very reliable engine. True?

what is the 8th letter in your vin code? Is it a "U" (single overhead cam) or "S" (dual overhead cam)

book time for doing the plugs is 1 hour for single overhead cam and 1.7 hours for the DOHC. (The DOHC would be for the taurus SHO)

Dielectric grease is good in moderation for your spark plug boots. never-seize can be used on spark plugs that have black metal threads but not needed unless you live where there is a problem with rust. Never-seize is not recommended for plugs with silver metal threads. They have stuff made in the metal so you don't need it.

A misfire on a cold start up that goes away after it starts to warm up could be a sign of a secondary misfire from spark plugs or wires. When the engine is cold it puts more stress on the ignition system. Spark will look for the path of least resistance, so any small crack in the wires or a plug will look to jump to ground rather than jump the spark plug gap.

It could also be a misfire due to coolant being a cylinder on start up. It burns off as the engine runs, miss goes away.Keep an eye on your coolant usage.
