Well, the P in the code means powertrain. As far as the code specifics,
P1313 Misfire Rate Catalyst Damage Fault - Bank 1
P1316 Misfire Rate Exceeds Emissions
I would say check your spark plugs and wires.
I've now changed all plugs and wires and still getting it now the far left wire on the MAF broke and I didn't get that code and check engine light stayed off but was getting a low input to intake air temp car ran good no bucking and jerking but would backfire occasionally on take off and didn't seem as much power but no random misfire I fixed the wire and random misfire came back

Thanx mate for taking the time to try to help but i have traced the problem back to fuel, the fuel pressure was way to high, due to the fact that it had dirty fuel in the tank and damaged the the fuel reg which is in the tank
