2001 XG300 Spark Plugs and the dealer

So, I also realize now that these three coils have to come off to get
to the three plugs under them.  Don't these coils go bad.  They guy at
Hyundai said they rarely go bad and they are very expensive to
replace.  God help that other dealer if he did something to the coils.

He's correct that they don't go bad very often, but I don't remember
them being all that expensive (for coils). They're easy to replace as
they're all on the front bank where you can get to them easily.

Does that apply to the Kia Amanti as well? I think they have the same
engine.
 
 If one goes bad, how would you know which one.  Does the computer
tell you that...does it tell you where the misfire is?

Indeed. The trouble code indicates the misfiring cylinder (if the
computer can detect that). Even without that information, as long as
the engine is misfiring during diagnosis, it's fairly easy to
performance test. If one of the coils is arcing, that should be
visible. Otherwise, you can a coil as long as you have an old wire
and two plugs. You can pull the coil and attach wire, putting one
plug in the coil and one in the wire and laying both on the intake.
Then start the engine and observe the spark intensity/capacity by
gradually pulling one plug and then the other away from the intake
watching how far it'll jump. You may want to wear insulating gloves
when doing this.

Probably. I've never examined an Amanti, but I see no reason why it
wouldn't use the same components for ignition.
 
hyundaitech,

You have definately gone above my pay grade. I'll change the plugs
and wires, as soon as I get a torque wrench delivered from Amazon. I
have everything else, and if there is still a problem, which there
probably won't be, I'll bring the car into another dealer. Since,
those coils are easier to get to than the back plugs, the charge
shouldn't be too much. Although, I am intrigued by the possibility of
diagnosing coils arcing. Unless, I just change one at a time.

Is ther a lubricant that has to go onto the threads of the plugs?

That shouldn't be necessary. I can recall exactly one instance (in 17
years) that I've had a serious issue getting plugs in/out of a Hyundai
engine.

All right - Alan went and bought himself a torque wrench. Don't stop there
Alan - you need to start drooling over a great big compressor, an impact
gun, and most of all - a set of torches. You really can't do any meaningful
kind of car repair without a hot wrench. Nothing says satisfaction like
facing a stubborn, won't budge an inch bolt, and lighting up the torches...

BTW - just remember to always store your torque wrench at its lowest
setting.
 
Mike,

The torque wrench never came from Amazon, it ships tomorrow. I
actually need to do this today or tomorrow because I have a case in
Trenton, 3 hours away, so I was going to buy one at Auto Barn. The
guy there told me these things aren't that accurate anyway and snug
should be enough. Besides, it was only $14.95 and it's not a "hot
wrench." Why are you talking about a compressor? Seriously, I am
attempting to do this and you are so condescending because I haven't
done it 40 years. I don't think it takes rocket science to change six
spark plugs and probably one of the easier things to do on a car and
all I worry about is getting things put back the right way.

Many people attempt there own tax returns and screw things up for
themselves. They never know if they did anything wrong until it is
too late. I'll know if something is wrong as soon as I turn the key
and if something is wrong, the AAA will tow the car to a gas station
and they will finish it.

Not condescending at all Alan. I've been watching your efforts since you
first brought up your problems and your concerns and have been encouraging
you as you've treked your way through the world of DIY. Happy to see a guy
step up to the task. At one point I indicated to you that I admire someone
who throws his hand at finxing his own car in this day and age, as it can be
quite daunting with today's cars. Most of us have grown through the
evolution of cars and have had the advantage of embracing the technology in
cars as it came along. That's an easier pill to swallow than jumping right
in today, in your own driveway or garage.

As for the compressor or the torches - pure joking around in the manner of
people who do their own work. There is this endless pursuit of more tools,
as you do more and more on your own. It becomes something of a joking
matter as we become tool junkies of sorts. Nothing at all intended to
insult you or appear condescending.

You don't have to defend your decisions to do your own work here - that's a
big part of what this group is about. Please take a second and re-read my
earlier comments from the perspective of being included in a group of people
that you are now joining, and hopefully you will see them to be inclusive
comments, and not insulting comments.
