Code p1313 p1316 p1111 p0301 means what?

Odd one this to have P1111 as well.

According to my data P1111 is all dtc checks compleated, however some websites show it as a Intake Air Temperature (IAT) Sensor Circuit Intermittent High Voltage, I'm fairly sure that the latter is incorrect.

check the basics first plugs, leads, corroded ground connections etc then its a bit of a guessing game

As for the other codes

P0301 = Misfire detected - cylinder 1
P1313 = Misfire rate catalyst damage - bank 1
P1316 = Misfire excess emission

Possible causes (as per JTIS):

Cylinder compression low
Worn camshaft / broken valve spring(s)
Fuel delivery pressure (low / high)
Fuel injector(s) restricted / leaking
Fuel injector(s) continuously open
Fuel contamination
Fuel injector circuit fault(s)
(Injector DTCs also flagged)
Spark plug failure / fouled / incorrect gap
ECM to ignition coil primary circuit fault
(Cylinder misfire detected DTC also
Ignition coil failure

hope this helps
