Where is spark plug located on lincoln ls 3.0eng 2002

The spark plugs in the v6 can become an involved job as the upper intake manifold. The LS uses a Coil on Plug (COP) ignition system, meaning that the spark plugs are located under the ignition coil

Generally in a spark plug is 60000 kilometers, if fuel is bad need in early, remove the spark plug, such as for auburn or rust color, spark plug showed normal; Such as stained with oil, shows that the spark plug gap imbalance or too much oil, high tension line short circuit or open circuit; Such as black smoke, spark plug type cold wrong or mixture is thick, the oil is up; Such as the top between the electrode and sediment, when for the oily sediment, shows that the cylinder into the oil has nothing to do with the spark plug, when the black sediment, spark plug carbon deposition and bypass, when grey sediments, is a gasoline additive covered electrode lead to lack of fire; If serious erosion, such as the scar at the top, with black pattern, electrode melt, showed that the spark plug is damaged.

My 2001 Lincoln LS V8 3.9 seems to have a slight miss when in overdrive about 1700 rpm's on an give i. t gas and it bucks and a slight miss. Have changed one coil pack, new spark plugs, new...

When you changed spark plugs did you notice any oil on the insulator or wire plug? Or any oil in the hole that the spark plugs are in? This model of LS were built with gaskets that seem to always fail. Lincoln came out with new gaskets in 2002 or 2003. If there was any oil in the above mentioned places your coils (COP Coil on plug) could be shorting out due to the oil degrading the insulator on the cops.The fix for this is to replace the valve cover gasket set with the upgraded set. Also it's almost impossible to find which coil is bad, and I recommend replacing all eight of the COPS. You can find them online pretty reasonable. I have used these and they seem to perform as good as the Dealer parts, but at a fraction of the cost. This solved the problem on my 2001 LS V8. Also these cars are known to have problems with the timing chains, which could also cause your problem. The adjuster shoes that keep the timing chain tight are plastic and wear out and come loose. Some times causing the engine to jump time and in the worst case could allow the pistons and the valves to come in contact. That will destroy the engine.

Ylinders Misfiring

you have to give it a tune up!!! According to your computer one of your plugs is fouled up so bad it cant get spark. So go to autozone go buy plugs, wires. thats the cheapest way. but if you want to get better gas mileage and keep your car in good running condition get the cap and rotor, and pcv valve, and a fuel filter. This is what u replace in a true tuneup. but if your tight for money right now just do those plugs and wires.

You don't have wires,you have COP-Coil-On-Plug system.
If you have the codes,you could change the coils yourself.Their $59.00 at the auto parts store.

There is a misconception about tune-ups.
You only have spark plugs,and air filter,that would need replacing,that effect engine performance (Tune-Up)
Also, you can Clean the MAF Sensor,in the ducting,between the air filter and throttle body,with CRC MAF Cleaner. You could spray the inlet to the throttle
body,but I wouldn't bother.
I consider plugs& filters ,general preventative maintainance,nothing really tunes the engine,but it's own processors.

If you remove the coil cover, on top of the valve cover,you access the coils.Have to remove the coils to get to the plugs. The plugs aren't your issue,unless they have been in the engine for years or the valve cover O"Rings are leaking oil onto the plugs. Three coils seems questionable.

Get me the codes!

O2 ls stumbles /misfires under power

could be timing, plugs, fuel or needing a decoke. Try a fuel additive and change the plugs and see if it helps. When you look at the plugs it should give you an idea of what the problem is.
