Top Issue- 02-05 Ford Thunderbird Ignition Coils COP

[bayfeet]

Bought ena coils and ngk plugs based on the link. Was not throwing any codes but the car seemed to be sluggish. Tough getting bottom 7mm bolts near firewall on both sides. What a difference! I guess after 20 years the plugs and coils were tired. Acceleration will snap your head back now. Thanks for all the info!

Only the people that fail to fix the underlying issue causing the spark plugs & COPS to fail suffer from this. Read post #1

2002-2005 Ford Thunderbird and Lincoln LS have a widely known issue with Ignition coils going bad and also fouling out spark plugs causing misfires
. Just by replacing these components, you may be able to bring new life to your engine!

At the time of this post, 59.30 for an entire set of Ignition Coils! Can't beat that! If you have a 2002-2005 Ford Thunderbird I would buy these just to have on hand because of the history of these going bad! Don't forget to order 8 spark plugs too because the coils foul them out!

Many people have had success with the coils above...

[H-Town 02 T-Bird]

I just bought my 2002 bird this fall my mechanic said the one on the second bank went bad because of a small oil leak in the valve cover gasket. so I had him replace plugs and both gaskets.He said that will take care of it.

This is true. Our 02 with 34K miles started sputtering. Didn't look for a code, just took it to an old friend who's a Ford man. They found a leak in the gasket which was causing the problem in cylinder 5. He replaced the gasket, the coil and plug. It was thundering once again. I'll get some time in the new year and go ahead with the other bank. This time gasket, coil packs, and spark plugs all the way around.
