i have a 2004 rx8 that has 2 codes P0302 and p2259. car runs like crap. already put new coil packs, wires, and plugs. my question is p2259, will it set the p0302? this car has set for about a year a friend brought it in and im just now checking this out. im gonna check the secondary air pump system out.but im kinda worried about the other misfire on 2 rotor code. i dont have a compression tester for this rotary. i want to check the compression.. any ideals ??
