I just got my 2005 Mazda RX8 back from the dealer. I thought for sure the engine was blown. P0301 check engine light. I have 173,000 on the original engine and just found out all it needed was new coils, plugs, etc. I thought for sure I'd have to put her down. Best, funnest, cockest (ok..grew up in the 60's and 70's) car I've ever owned or driven. I bought a Mazda MX5 RF 2 years ago and it's so tiny next to my RX8 but it's just not the same.
