2000 MX-5 Miata Misfireing

I bought my 2000 Miata in May '08 with 7500 miles. It ran fine (as one would expect) for the next 1400 miles or so. Last week, after a short stop, the car misfired horribly upon startup. I shut it down and looked for the obvious and saw nothing. I was in a very rural area with no available assistance, so I drove the car approx. 6 miles to my home. I looked under the hood again and noticed that it had Autozone replacement plug wires. I thought that was odd since the car had such low mileage. I inspected and re-installed the plug, then found a loose connection at the distributor. The wire had come out of the metal contact, so I figured I found the problem. I re-inserted it the best I could, and the car started and ran fine. Next day, I bought a set of NGK wires from a Mazda dealer knowing that this was the answer. I started the car and it ran as lousy as it had the first time! I turned off the check engine light be removing and re-installing an underhood fuse, then walked away from it for a couple of days to soothe my nerves. When I decided to tackle it again, the car started and ran fine, and has done so twice since. The check engine light is back on, but so far, the car runs well.

Can anyone point me in the right direction? I won't be comfortable going any distance until I get to the bottom of this.

Thanks, Chuck

You are showing the classic symptoms of a failed coil pack. I think you can get one for about $230 from rosenthal mazda (finishline performance)

Mazda 2000 MX-5 convertible, 85000 miles.-check engine light remains on. Have replace the crankcase sensor. stalling quit. Both catalatic converter sensors replaced. do I need to replace the CC now?

It depend on the code. there are a lot of things other than the O2 sensors. Have it scanned and bring the code back to this sight so we can tell what the problem is.

Most Advance and Autozone store will scan it for free.

Hope this helps

One or more of your O2 sensors has fouled, sending erroneous info to your ECM. You'll have to visit a mechanic on this one, sorry.
Look for repair to average $80 per sensor (you may have 3!)

A cheap fix is as follows and not 100%-Advance Auto Supply store buy a can of "SeaFoam" and add to gas as instructed and drive at least 100 miles.
Good Luck

Have you checked that you have power to the coil on cranking?You may also want to check wether you have a good strong spark at the spark plug.It could be an ignition module breaking down.If you have no power to the coil you may need to change the ignition relay.Its close to the battery.
