2004 rx8
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 ??

P0302
POSSIBLE CAUSE
• When the eccentric shaft position plate or the engine was replaced, the learning value for misfire determination was not initialized.
• Eccentric shaft position sensor malfunction
• Spark plug malfunction
• High-tension lead malfunction
• Excess air suction in intake-air system
• Fuel injector malfunction
• Leakage engine coolant
• Insufficient compression
― Metering oil pump malfunction
― Engine oil condition malfunction
― Rised oil pressure
― Oil passage malfunction
― Engine malfunction
• ECT sensor malfunction
• Fuel line pressure malfunction
• Fuel pump unit malfunction
• PCM malfunction
P2259
POSSIBLE CAUSE
• AIR solenoid valve malfunction
• Connector or terminal malfunction
• Open circuit in wiring harness between main relay terminal C and AIR solenoid valve terminal A
• Short to GND in wiring harness between main relay terminal C and AIR solenoid valve terminal A
• Open circuit in wiring harness between AIR solenoid valve terminal B and PCM terminal 1O
• Short to GND in wiring harness between AIR solenoid valve terminal B and PCM terminal 1O
• PCM malfunction
