I have a 2004 mazda rx8 and it just started this the last couple days ill start it and as long as my foot is on the gas it wont die but the second i take it off it dies and after a couple cranks it will go up and down in rpms before starting to idle and staying on. Even started dying when coming to a stop just about every time threw a scanner on it and got these codes... my question is could these codes be the cause of whats going on ?
