Hope it helps.

I have been following these threads out of curiosity because I have no yet experienced these problems. Want to be ready for future events. A brief search today brought up this ad (posted here because of low price and free shipping)------

What I can not understand is how a plug could unscrew that far in normal driving. I see no reason to replace the good coil packs. Since you have 82k miles, I would just go ahead and replace all of the plugs and the one bad coil pack.

While replacing the other plugs you will be able to check to see that all of the remaining plugs are in tight. If the one hole is damaged, probably only the top thread (or two) is damaged. If you can not restart a new plug in there, get a tap and chase out the threads. If it is really stripped then you will need to get a heli-coil kit and install it. Ask at a good autoparts store. They should have heli-coils.

Oh yes, look up the torque spec and torque the new plugs when installing them. I'm guessing it should be around 13 to 15 foot-pounds but LOOK IT UP to make sure. On aluminum heads I always use a very little bit of anti-seize on the threads. Do not cover the first two threads and do not get anti-seize anywhere near the electrodes.

Lot of companies make anti-seize. You can find it at AutoZone or your favorite parts store. Get the smallest container you can find and it will last you for years.

Good Luck

I fixed it. The only pain in the butt part was getting the intake off. Trying to find out where all the bolts were was hell but very easy putting back together. The spark plug was loose, I tested the threads before I even thought of buying anything. I have pics but don't feel like posting them and hearing people whine about them being big. (Not surprising, everyone on here does it.)

but yea I noticed that it runs a lot better and isn't bogging down. I also removed the rear seats, (I don't like giving a lot of people rides.) So now its the front seats, thinking of doing some sort of sound system setup for the back, putting one sub behind the front seats, should sound good. (Off topic sorry.)

So manout, thanks for showing me my coil packs. I checked them I see nothing wrong, but I think I dont know what i should be looking for. If they are bad, should they rust, crack what? cause i don't see anything wrong. When I mist them what should happen if they are bad. Need to know. my dealer says i need 4 and that is going to run me close to 50grand in Jamaica.Help

Mostly there won't be anything visible just looking at them, though visible signes of wear are a good clue. Misting them with the engine running will cause them to arc which should be visible BUT not all bad coils will do this. Easiest way to find the bad one is to buy 1 new one and just install it in eack Cyl in turn until the problem goes away. This works great unless you have more than one bad coil.
