I have a 08 6 speed manual rx8 and I've been having trouble with it for over a month now. It cranks and takes forever to start and floods itself while cranking so when it starts it throws tons of white smoke from exhaust its idles fine after but stalls out when I'm driving. It will just shut off rolling to a stop in neutral. I've tried new plugs, wires, ignition coils, a new MAF sensor and none helped. Please help I've been going to the car meets for the past month in my family car and I need my rotary back lol.

 

If it stalls when it gets warm it's most likely compression. Will it start back up and idle after it stalls?
Are there any codes?

 

at first there weren't any codes but now its saying it's getting too much air bank 1
Took it to do a diagnostic w a side mechanic and he said my computer doesn't have communication with my cam sensor. Which is the eccentric shaft I was told.
it runs beautifully when it's on so its strange.

 

Then perhaps try the 20 brake stomps to reset the ESS?

It's quick and cost you nothing.

 

Check and clean all grounds and connections. They are a huge deal with all the electronics in our cars.
There are a few grounds directly on the top of the engine block Underneath everything

 

Any news? I would do what what Red line envy said and If that didn't work, your code sounds like a vacuum leak to me. I would check all the vacuum lines for splits or cracks and do the same with the intake manifold.
