Mazda RX-8 won’t accelerate

Hi all! I recently rebuilt the engine, ported the housings, and slightly upgraded the apex seals because I’m planning to install a turbo in the future. But back to the issue. I put everything back together, and now the engine runs rough at idle, the idle is unstable, it is stuttering when I get to 5 Rpm and higher and it keeps cutting off on me.
by the way my spark plugs is new, battery is new, alternator is new, coil pack is in great condition.
