Thanks to Leon, Nora, and others, my "Green Hornet" is really running great. My check engine light came on last week...again. A couple of months ago, I had Mazda install a new cat converter, under the emissions warranty. Then I found out that the ignition coil was the probable cause for the cat failing in the first place. I had a couple episodes of the ignition coil failing, causing the car to backfire and run really rough. I bought a new ignition coil from Trussville Mazda, along with 4 ngk plugs. I got some really nice
8mm Magnecor plug wires from FlyinMiata. So my question is...should I have Mazda replace the 2 month old cat? I've got 3 years and 15K miles left on the 8 year, 80K mile emissions warranty...maybe I'll just wait until the remaining time is up, before getting (another) new cat. Thanks for your help! jim- posted
