Yes, it did.
You'll get random misfire codes, then eventually Ignition Coil Module A (or B, C, D, E). So it will tell you, eventually.
Make sure to check that wiring harness, especially the middle wire, for problems...otherwise your expensive new coil might start throwing codes within a week or two and you might think it's defective.
Ok thanks, yeah, I replaced the entire wiring harness with new OEM 10 days ago, along with the plugs.
