I'll probably come down to aaron's house wednesday
My coilpack went bad(10k miles after warranty), not that much of a shock though there are some out there with lower mileage than me who've had to replace thiers.
99-00 original factory coilpacks have a knack for having a short-lifespan, about 20 people on the miata.net forums have had them replaced. Seems like an issue that affected many but not enough to send out a service recall.
I ordered mines last week, came in today. I'll be putting it in wed.
For some of those that know, my check engine light was on for a while. I had originally thought it was the 02 sensor or at worst the warm-up cat which is what the odbII scanner was giving me. I took it to the dealer because federal emissions warranty is 96k miles, free replacement cat.
Turns out the Coilpack went/or is going bad, causing a misfire in the ignition system and crapping the cat out. I remember how fouled my spark plugs were when I last checked them, the idle was a bit higher and rougher, there seemed to be somewhat of a drop in power and there were the few times that the engine would run on 3cylinders until I resetted the ecu by disconnecting the battery cable.
So they didn't charge me a thing and tell me once I put in my coilpack, bring it back for the free replacement cat
