Misfire on the #2 spark plug

I found this for firing order.

The error code 302, means misfiring at cylinder 2 while code316 means misfiring detected in first 1000 revolutions. The reason for misfiring may be faulty spark plug, faulty plug ground connection or can be damaged wires.

Go to Auto Zone or O'Reillys and have them hook up the code reader. The reader, if there is a misfire, will tell you which cylinder is not firing. That's your culprit. The firing order diagram is available online or in the store. It will tell you which plug is which.

Replace the plug. Ensure the gap is set correctly. That should be the end of it. If you really must visually inspect for spark then after pulling out the plug, re-attach the spark plug wire. Hold it by the wire end, where you are touching rubber to protect from shock. Have someone turn the engine over slightly. You wont have compression in the engine as the plug has left a nice size hole on the cylinder. But a turn or two of the key should produce a spark or two on the plug. If you dont see a spark, you may have a bad plug wire.

I'll bet you a $3 bill that your trouble is fixed back at step one. Replace the plug.

Do a leak-down test or at least a compression test

USING WRONG TYPE SPARK PLUGS. THE SPARK PLUGS TOO LONG.

The spark plugs won't misfire,that was a waste of time,
unless they were in the motor 3 years or more,60,000
miles or more

You got a MIL Lamp on, and a code

Why are you not diagnosing that code, for issues

A Misfire First 1000 Rev, should also have cylinder codes
PO301 thru PO306

sounds like your wires are switched around. have replaced the plugs lately

I am assuming you have the 3.0L Duratec engine. Although the job seems daunting, it's actually easy to remove the upper half of the intake manifold plenum. This took me about 40 minutes to remove the first time I did it, and leaves the rear three spark plugs wide open.

A good repair manual such as the Chilton's manual for the 1996-2005 Ford Taurus has the step-by-step. You should get a new set of intake plenum seals (from Ford or most auto parts stores, which may have to special order them) along with the spark plugs. The seals are a set oval rings made of silicone rubber. Yours may not need them but if you damage one getting the plenum off, or if they have shrunk with age, you'll be glad you got them. They're about $16 a set.

What is a Taurus 2 cycle??? When does it misfire? Report fully!

Quick and simple solution is change the spark plugs, use the plain platinum type, and the spark plug wires. When installing the plugs, be sure to use antiseize compoud on the plug threads before installing them. The proper spark plug gap will be listed on a sticker label under the hood. It helps to remove them air filter assembly and duct work to get easier access to the back three plugs.
