shaking, please help
Well I did everything I changed my spark plugs, coils, and checked for a vacuum leak and they’re all good but my car still has really shity idling and shakes. And it only happens when the cars warmed up. Also it gets worse as I drive it more and the car warms up more. Please someone help me. im so lost, I don’t know what to do anymore.

I have a 2004 rx8 with 31000 and all I’ve done to it is mazdaspeed intake and exhaust. Oh and also I have a lot of unusual back pressure, the exhaust pops a lot more than it used to.

Do you get any CEL? Misfires?
Do you have the latest flash?
Have you looked into the motor mounts?

back pressure is caused by restrictions in the exhaust. IE. catalytic converter, turbines, small piping, etc

No it’s a manual and I do have Misfires. I think it has something to do with the intake because it started doing that ever since I put the intake on. Btw thanks, I really appreciate you guys trying to help
