Help newbie engine codes

[domg]

Hello I am new to all of this I am looking to buy a car it is cheap for this reason the car will start fine and runs fine when cold but once it is warm and think come off the chock cycle it tick over really rough up and down I have had a friend read it with a code reader not sure what make (sorry) and they come up with a p000016 think it was that many 0'smight be one less sorry and then he cleared the fault started the car again and it came back with the same p000016 and a p0314 again that might have another 0.my friend says it sounds like the timing is out as it is popping through the exhaust so his money is on that but he said a good place for help is a forum as you might have seen it before does anyone have an idea what it might be

I have done a search but nothing back as exact as mine

O and the emissions light is on my mate thinks it is only on as the oxygen sensers will be reading to much fuel in the exhaust

Welcome to the site.

Would appear to be P0016, google the codes & gives you a general idea, timing is one thing is seems to point to yes, P0314 could be cylinder misfires, caution advised:

Althought for different cars, it gives you an idea what it could relate to
