I meant to submit a picture, but if you’ve seen one ignition coil, you’ve seen them all.
Okay that’s absolutely not true. Not true at all…
First one I bought, from a “guaranteed fit” website, did not, in fact, fit. My car has a 4-pin connector for the coils. This one had only three. So back it went. Went to the dealership and got the correct coil, which is what I should have done in the first place. Serves me right for trying to save a couple bucks…
Swapped it out and goddamn it’s like having a whole new engine! I had no idea one sickly coil could make that much difference in an engine’s performance. This thing much have been bad long before it started throwing codes.
The old one looks fine on the outside. I’d imagine whatever’s bad is somewhere inside the epoxy, which I’m not going to bother digging through to find. Cleared the engine code and I’m gonna hold on to the old one just in case.
First time doing this too. Had no idea it was that easy. I’m not really a car guy.
If it’s a dual fire coil design, then a 4 cylinder only has 2 coil packs, each pack delivering spark to 2 cylinders simultaneously. So on those, if one coil pack goes completely bad, then you haven’t lost 1 cylinder, you’ve lost 2 cylinders!
Yeah, that’s happened to me before, half the fucking engine went dead, and I just barely could make it home, while my passengers couldn’t have cared less and just wanted me to drive them around, probably to go get some weed.
I had to tell them to fuckoff, either get out of my car, or you’re riding back home with me while the car still half runs, cuz the next destination is to park it at my place until I can get it fixed.
Those dual fire systems are … interesting … to say the least …
