Just got my car and now its throwing two codes. Misfiring and throwing smoke rings on cold starts frequently nd does it less upon warm starts.
Throwing code P0300 random misfire and P0302 rear rotor misfire

New plugs and wires from the previousowner just before I got the car I will test them this afternoon but what elese could it be? I've read somewhere that it could be a fuel pump issue as well. Anything else I should look out for?
