Dropping a cylinder at low RPM under load. Plugs are only 1-1/2 years old with maybe 5,000miles - I don’t drive this car very often. All the boots were pretty well shot so I replaced them - no change. I’ve read that coils rarely go bad but I’m pretty sure I’m in that “rarely” percentage. I can’t find replacement coils with this same yellow label - I feel like these are not OEM. Thoughts? Recommendations?
