I recently bought a 2005 Rx8. 68k miles on now at 76k. I have replaced the spark plugs, air filter, starter and crank shaft position sensor. Im having starting issues though. When its cold it starts right up. when i run it around town and turn it off, it will not start. if i let it cool down it starts right up again. how do i fix this? this is really becoming frustrating.

 

same thing happen to me and do u lose performance alsoo and having weird sound when reving high ?

 

nope. runs great when its started. just getting it started is the problem.

 

dont wait till its too late. i did and i believe i need a new engine. Either go ahead and get it to mazda, or go ahead and get it rebuilt. It will save u some headache.

 

Go to your local mazda dealer and tell them that you are having a hot start issue and would like a compresson test done. I had one done last week and they only charged me for labor so it was only $80 bucks.

My 05 with 72k is just with in the lower limits of whats acceptable so I think by the fall I will have it done again to see if it still passes.
