Ok, so the other morning I went out to start up my 2004 manual Rx8. It started fine and I went back inside to let it warn up (it was only about 10 degrees that day). I came out about 15 min later and notice the car was sputtering. I got in and the cars CEL light was flashing. I backed it out gave it some gas and it stalled. It started right back up but with the same symptoms. I put it in first and started moving. The engine seemed like it didn't want to rev or even move. I put it in neutral and kicked up the rpms. I put it in gear and it finally caught and seemed to go and the CEL went off. I haven't had any problems since then and everything works. Any idea what this could be??

Thinking dude. I'm in Florida............it's warm here!
Will be interesting if it comes back. It could have just been a hiccup and maybe never see it again?
Year?
Miles?
Flashing cel is usually a misfire. Could have a loose plug wire(check them on both ends), or a coil beginning to go bad, or a bad plug wire itself.
You have a way to read the code? It will be stored.

Yeah, I mean its fine now. I make sure to let it warm up to full temp before running it now though. I also am going to start putting premium gas in instead of regular... I heard it didn't really matter.

as a general rule the renesis likes a bit higher than 87 octane (91 actually). I know people claim 87 is fine, but it definitely isn't in my 8.
trying to think of an easy way to explain why a little bit higher octane is better. Anything over 91 is probably waste fwiw....
ssssoooo, Look at it from a timing perspective -- gas enters into the chamber, hangs out with oxygen, they then swing with the rotor into the combustion chamber and the plugs light and bang, pop, wow, rotor spins. A lower octane fuel could ignite sooner than later, burn faster rather than longer, and not give the rotor the optimum push it needs to spin into the next cycle.

def start putting higher octane in it i had the same type of prob one time i ran 87 and it's been nothign but 93 and premix since then.....like mazurfer said i cold b amisfire from a loose wire/bad coild something like that would not hurt to check the plugs/wires/coils.....
