have you tried giving it a jump? you probably have either a bad altenator or starter. both are cheap parts and quite easy to fix

go to the next web and proceed according :

God bless you

Odd one this to have P1111 as well.

According to my data P1111 is all dtc checks compleated, http://www.bluejag.co.uk 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
flagged)
Ignition coil failure

hope this helps

Stretched timing chain it appears to be your problem if back firing

To clean your ECM codes just disconnect the negative battery terminal for 20 seconds.. no biggie.

check lock up solnoid

Take your battery cables off the battery and touch them together for one minute and then replace on battery...check to see if codes have been cleared.

more likely need to replace cluster, known problem, remove it take to your local napa they can send it in for repair.
