Hi,

Just after a bit of advise.

I started my 2004 RX8 this morning and it sounded like a tank (real lould and rough), when I moved the car had no power and the engine management light flashed as it missed fired. After about 1-2 minute of loud roars it was fine and drove normal still a slight misfire when was idel.

This was serviced over 2 month by mazda and nothing was reported then however I do have a rattle from inside of the exhaust .

Any ideas or help is much appreciated.

Tons of info there for you. good luck and post back
