I have an 04 a/t rx8 with nearly 40,000. 90% of the time this is my dream car, and drives and handles like butter. But on some days the car shakes pretty severely when in idle at stop lights and such, and I have even had the car die on me a few times. Also quite often when i drive, starting out I will step on the pedal and the car will barely go, then all of a sudden it revs up really high, jerks, and the transmission sounds funny. I am a college student and can't afford to pay for repairs, just wondering if this is really bad, or ok. and how long the normal life of the engine is? Thanks!

40k, Plugs and Wires. and go from there.

the engine itself has no problem normally, just check starter, coils, plugs, if you have a cel on, check the cat, but if you feel a major loss of power, then thats probably the engine. but not all of the rx8s have engine problem....dont get me wrong, you know how rotary works right?

The question I have is at what point will carbon buildup start causing problems and what problems will it cause? You really have no way of telling if you have a carbon buildup problem. Nobody really knows if the redline a day theory actually does anything to burn off excess carbon either.
