So my 2004 rx8 with 120k miles on it, is giving me two big problems now. CEL came on a few weeks ago, had it checked in autozone, reading bank one and two too lean. Now, when I turn it on when cold it shudders and misfires and CEL light flashes. The canister by the exhaust is one while this happens then turns off within 30 seconds. Idk what it can be. Now it seems to be running hot, keeps over flowing coolant but not over heating. Ae these two problems the same issue? Some help please!
