hi guys,

I just bought an RX8 and new to rotary engines. it's 2008 series 2 automatic with paddle shift. it has around 38,000KM on the clock.

I noticed that the when the car in in idle the rev meter goes to around 900RPM in oppose to 1000RPM (In park neutral and drive). this cases a small jerk in the car which can be slightly felt.
does anyone know why this happens and what i should do to stop and make it smooth again?

Thanks for all your time and advice in advance
