Change cam sensor & erase codes.( disconnect battery for a minute or so after.) 340 & 1391 refer to cam sensor problem, and all other 300 codes are cylinder misfires that should disappear when cam sensor fixed.

Check all tubing and junctions for leaks in the fuel evaporation control system. The ECU has detected an issue with intake manifold pressure and is indicating that fuel vapour recovery system is perhaps to blame. Sometimes this can be connected to a fault in the manifold differential pressure circuit which lies on the vacuum line leading to the EGR valve. Also quickly check that the EGR (exhaust gas recirculation) valve is OK by connecting and reconnecting its vacuum line and listening to engine note changes. No engine note change indicates the EGR is probably jammed shut with exhaust crud and needs a general clean up. Sometime these codes detect the symptom and not the cause so you just have to work your way back and eliminate what it might be.
