When you change plugs, do you go ahead and change the coils or wait until they go out?
Thanks.

You wait until they "go out".
Change the plugs as per the the manual (and the wires, if any), and your coils will outlast the car.
Wait until they go bad... if they ever do go bad.
Thanks for the info. Much appreciated!
Depends what kind of car and how much mileage is on it.
There are some Ford models where the ignition driver module ought to be swwapped out in a tuneup, even.

oh, they do. All the time. I can count on one hand the number of times I have seen an old fashioned external single barrel-style coil go bad. COP on the other hand?....all the time. Some mfgr even have TSB on replacing ALL of them for misfire codes (Ford), and "primary circuit malfunction codes" (Nissan).
If the coils have boots you can replace, those should be done with the plugs as maintenance. They don't fit tightly on the plug once they are old. GW
Interesting! Thanks Geoff. I will remember about the coils.
