WTB: NB2 ignition coil for my DD miata

[Dustin1824]

Anyone have a NB2 ignition coil that's in known working condition?

I am 95% sure I have a bad ignition coil. Woke up this morning to go to the dentist, got in the car, and it had even less balls than usual when going up a hill.

The car stumbles under load. Eventually got a CEL, scanned it and got the code for cylinder 2 misfire. I swapped the coils, cleared the code, and went for a drive. Car stumbled again, and got a new CEL for cylinder 4 misfire. Since the misfire moved with the coil, I'm pretty sure that's it.

Anyone have a coil they aren't using? I'd even pay to just test a coil if you don't want to sell yours or if it's on your DD. Just want to get to the bottom of this, and it takes a long time to get a new coil from mazda.

Any help appreciated.

I might. Here's what I have.

For the NB2's aren't the coils on the plugs, i.e. integrated into the plug wires? Like this: http://parts.arlingtonmazda.com/prod...252d9U%29.html

The '99-00, '96-97 look more like the picture above, but the plug is different: http://parts.arlingtonmazda.com/prod...252d9U%29.html

The NB2's are pretty much a hybrid. Cylinders 2 and 4 have the coils on the plugs. From the coil on cylinder 4, there is a standard plug wire going to cylinder 1. From the coil on cylinder 2, there is a plug wire running to cylinder 3.

I think I may have found a set locally, the guys at MER have a couple spare coils they are willing to sell, and they are open tomorrow. I'm going to get my spare diff checked out to make the trip more productive.
