"Boot" under coil pack

[Torinate]

My truck has been misfiring and the spark plug boot under the coil pack directly to one of the plugs is brown and cracked. I bought new plug wires for a ridiculour price and they weren't included. WTF? So much for a new set up wires...

Why isn't it included? Where can I get one?

Anyone have an extra one lying around?

Thanks

probably have to buy the coil to get it. You can wrap some electric tap around it as a temporary fix though. Ghetto, but i've done this on a set of plug wires or two waiting for a new set to show up at the dealer.

Buy the whole coil to get the rubber boot... It should have been included in the set. It's kinda like going in to buy 24 beer, paying for all of them but only getting 12.

Sorry, just frutrated. Also, why is it that no-one here in Ontario carries any brake lines / fuel lines in metric? Baaa!

The boot you are referring to is not part of the wires at all, it's part of the coil pack so there is no reason you should even expect to get one with the wires. That's like buying new tires and complaining that they didn't come with new wheels.
You should be able to get a new coil for about US$90. If you had researched the problem better then you wouldn't have needed to buy new leads in the first place. See if you can take them back.

You can buy just coil boots.

Lol!

Not part of the wire set... Still trying to figure out the analogy of tires and wheels. The coil is an electrical component "making" the spark. The boot is exactly the same as the wire set. It is the same as the end of one of the wires. Exact same purpose in shielding the spark pug. Has the exact same purpose, has the exact same location but is obviously shorter in that the wire only goes from the coil to the plug. Oh wait, so do the other wires - go from the coil to the plugs. They're a separate piece. They're not attached to the coil. It's more akin to buying an 8 pack of crayola caryons but only getting 6 - no white or black because they're not really classified as colours.

No matter though, it's just a way for the dealers / parts people to jack up the cost by only selling half of you need so they can make 2 sales. I get it.

New coil at my dealer is $135 including taxes. Ridiculous when I only need a rubber boot...

As a medical person, isn't it frustrating when you go to the doctor and they will only look at 1 thing per appointment? I guess it's the same logic. Inconvenient, pain in the butt and not fair; but you get my drift.

Thanks for the tip on where to purchase.

I will follow up with them.

Did you test the coil that has the bad boot to see if it's within spec? The coil might be the reason the boot went bad. This happened to me last year. I can give you the test specs if you want.

No, I didn't test the coil pack.

I did insulate the boot better though. Miss is gone now. I could see the crack in the boot and it is discoloured (brown). Truck runs fine now.

It could be the coil pack that caused the boot to crack, but would it not still miss and run rough?

Here's another beef. Changing the fuel filter. The front line was rusted into the filter - absolutely no way to get it off. So, I just cut the line and thought I would just buy a new nut and re-flare the end of the line. Well, no one sells a flare nut with 14m x 1.5 thread! Absolutely no one! Canadian tire sells me a new filter and a new line. But of course, the new line is imperial, not metric. Doesn't work. So, I go back up there and they can't even get one. No fittings, no nothing. There's not a parts store in Ontario with 14mm x 1.5 threads or a line with them. The imperial line (51") is $8.00. But, nothing in metric. So, to the dealer I go. Yes, they had to order one in at a cost of $68.00 plus tax - for a 4' 5/16 fuel line! At least the guy gave me a wink and a polite thank you on my way out! Unbelievably ridiculously overpriced!

Yea yea, i'm ranting. Sorry. I just hate it when I get taken for a ride! Of course, I could have had them change the filter for me for an hour and a half shop rate!

Anyways, what are those specs for the coil. I guess i'll check that now just to see...

PRIMARY COIL RESISTANCE. Using an ohmmeter, measure the resistance between the postive (+) and negative (-) terminals where the connector plug into the coil pack.
Cold 0.67 - 1.05 ohms
Hot 0.85 - 1.23 ohms

SECONDARY COIL RESISTANCE. Measure the resistance between the positive (+) and high tension terminals.
Cold 9.3 - 16.0 ohms
Hot 11.7 - 18.8 ohms

If resistance is not as specified then the coil needs to be replaced.
