Hi, my name is Eric, i'm new to rx8's, have just done my first engine rebuild on a 195bhp engine and everything seems to be running well but i'm having a problem when cruising, the engine can rev well with no issues or warning lights trough the gears but when cruising as soon as I go over 4000 rpm I,m getting a misfire code(cylinder 2 misfire), if I stay slightly under 4000 rpm everthing is perfect, also idle is a bit rough, I've replaced coils and plugs, anyone any ideas, thanks.

See the misfire thread in my signature. Lots of things it could be.

Check injector wiring for errors

Thanks for the info, the ssv valve was jammed open, a good clean sorted it out.
