Either the spark plug or the ignition coil on cylinder two is faulty. Replace and check if code goes away.

do you have ant idea how mus=ch a coil cost and are?

Sure do, about $50-$60 and get a set of plugs too, $2 a piece. I failed to mention that depending on your model year, you might have spark plug wires vs Coil on Plug. The parts can be bought at any auto parts store or online retailer. Here is a video that might help.....http://mazda-repair.blogspot.com/2013/02/how-to-mazda-mx-5-miata-changing-spark.html

There should be 2 coils but both part of 1 assembly on a Mk1, the coils do go faulty, I have a Mk 2.5 2001 mod el with 2 coils sat on the top of the engine & get very hot, both have had to be replaced. When you think about it the coil pack is probably one of the most stressed parts of the engine.
