got a low oil pressure message and after driving a while longer started idling rough then check engine light came on got po300 po301 po302 po303 po304 codes,replaced plugs with ngk factory original still idling rough

 

need a little more info here...what engine, year, have you checked your oil? did you change spark plugs? change your coil packs? any engine sounds? probably should of stopped driving it you got the oil light, that usually means you've lost pressure or you're low on oil and need to add more. I'm thinking coil packs are your misfire problem 90% of the time it is on these cars.
