Mazda RX8 After 5000 RPMs No Acceleration?
Im having a problem with my car its a 2004 mazda rx8, Manual. I basically cant open my car up past 5000 RPMs. Its fine until im driving it for a while, I cant shift a 4000-4500 RPMs no problem but as soon as i bring it past 5000 RPMs it makes a weird sound almost like something clogging it, After that i have no acceleration at all. Anyone know what this could be? I just replaced my ignition coils, Plugs and wires. I used two cycles of fuel injector cleaner and i bought the mazda decarb from the dealership and cleaned the carbon out of my engine, It still didn't fix the problem

Is the Check Engine Light on and have you checked for trouble codes?
