So I fillany got my spark plugs from the RX7 store (witch they took about 2 weeks to get to me and they are wrong). I bought new plugs thinking that was the reason the car ideals rough and why it sputters in high rpms. I also bought new wires. Well I was wrong. The car still sputters and pops at ideal and high rpms. I have no clue what to check for next.

Any ideas on what it could be?
