I’m replacing spark plugs on a mazda mpv and I want to be sure the coils are ok to reuse or need to be replaced. I’ve measured primary and secondary resistance values and they are all close, but I can’t find the specs anywhere. Thanks for any/all ideas.
If you don’t have any misfire codes and the the coils aren’t physically damaged, I wouldn’t bother replacing them. If the boots are available separately, I would replace those, given the age of the vehicle.
