My Miata has been idling roughly for a while now, but it never happened very often. When I went to go get myself some tacos from Jack N the Box the other night, she idled terribly, and the CEL (check engine light) came on. I scanned my car to get the code, P0300, which is the code for multiple cylinder misfire. I knew that one of the things I've been meaning to do is change my plugs and wires.. and I did. She ran fine that night, and throughout the next day. It wasn't until the night of the next day where I thought I was going to have problems again. She would start to idle sooo low, that it felt like she would stall when I would stop at lights and signs. So I got her home and now she is parked.
After doing some research, I've found out that the 99 and 2000 Miatas have problems with their coil packs. That fits my problem well, as a faulty coil pack can cause an engine to misfire. Tonights agenda before class at 7, is to replace my coil pack, air filter, and to clean my o2 sensor and my throttle body. Hopefully this solves my problem, and hopefully I can get it done before class so that I don't have to keep driving around my step moms car.
Will post back with the results, wish me luck!

After replacing the coil, she runs great.

Goodluck in getting your baby fixed!
Hi Chris, found your post on google; I seem to be having the same problem with my '99. Just curious -- where'd you buy your coil pack? I'm looking around online and the prices are through the roof. Also, did you use the installation guide from miata.net? Thanks and hope to hear from you!

Hi Kyle, I tried following the link on your name, but your blog isn't public..so I'm replying back here.
I bought my coil pack from my local Kragen store. It cost me about $170. They get pretty pricey when you buy the whole packs.
Yes I used that exact guide on miata.net, I love that site! ;) haha. I followed it step by step and had no problems.
Good luck and I hope you get your miata back on the road soon!
Hey Chris,
Thanks so much for the reply. What exactly did you buy for $170? Did you just get the coils and not the housing? Found this on Kragen's site for $245: http://shop.oreillyauto.com/ProductDetail.aspx?MfrCode=BOR&MfrPartNumber=E752&PartType=190&PTSet=A, which was all they had listed with regard to ignition coils.
yeah, I was way off in my quote. I pulled my receipt and that is what I paid. I don't know what I was thinking of XD
Ah ok -- thanks again man. Looks like it's time to spend some money...
