The car at an idle will bog down! Idk like it will idle up then way down and it sounds like its missn. I have a mid pipe, cai, exaust, I just replaced my plugs and coil packs! And cleaned my cai! The exaust now sounds diff. Ever since it started this! Any ideas? I have 44k on my rx8 its a 06 idk if that helps
