What is the service life of coil pack?
What is the service life of coil pack?
What is the service life of our coil packs? Is it supposed to be changed at every basic tune-up?
Is there a high mileage owner still on the first set?
Thanks

As far as I can tell, there is no indication in the Helm manual for a "routine" change interval for our coil packs. There are tests that can be done if there is suspicion of a malfunction. I suppose these things can go a week after you get the car. They can also function perfectly well for the "life" of the car.
Traditionally, "coils" were changed when they've had anywhere between 50K to 100K miles on them. It all depended upon the symptoms present at the time and whether or not the owner just "felt like" doing it since they weren't that expensive.
Our coil packs, on the other hand, aren't cheap and there are 4 of them.

Xviper,
About the test you mentioned, is this something that can be done with a simple multimeter? or Do I need you take it to the dealer?
If the test can be performed with a multimeter, would you mind elaborating?
Thank you

Are you talking about the spark coils? If so.....My $.02 worth:
I've never considered changing a coil unless is was bad. And if it is bad, you'll know, because you will not get spark on that cylinder. My '71 Porsche had it's original coil. My '91 Alpha did not, because it failed & the car had no spark.

OK, I've had a chance to look in the Helm manual. There are no "at home" tests that you can do. I believe Honda meant for these to be a "non-serviceable" item and you simply replace them if there is suspicion of malfunction. The output from these things are in the tens of thousands of volts. It is not recommended to try to take any readings from these at home.
Your Honda dealer tech "may" have specs on them and might be able to do a diagnostic to determine if they are within acceptable ranges. However, I have a feeling that with most modern day coil packs, the manufacturer do not want anyone playing with them.
If a coil pack was malfunctioning, the ECU would most likely throw a CEL with a code for a misfire. However, the converse may not be true (ie, a CEL may not necessarily mean a bad coil pack.)
With the old style coils, you could go to an autoparts shop and they could check the resistance and tell you if you needed a new one. It was no big deal as they cost only about 20 bucks.
