DTC P0420 Catalyst System Low Efficiency Bank 1
You will find a bad O2 Sensor behind the converter or a bad catalytic converter on the bank 1 side of the exhaust manifold. This is the one on the drivers side.

P0113-Intake Air Temperature (IAT) Sensor Circuit High Voltage
P1111-Intake Air Temperature (IAT) Sensor Circuit Intermittent High Voltage
I am unable to dig up any C code with that number.

Error code P0300 means that you are having multiple/random cylinder misfires. I would start with changing all of the spark plugs and see if that will fix it. You will have to have the code reset at an auto parts store. If that doesn't work let me know and we can progress down the line.

po200 is a injector circuit issue. the 300 is most likely related to it.. There is a good chance you have a PCM issue that needs to be looked at. No way to tell whats going on without diagnosing . This will leave you stranded if you don't deal with it soon

A P1415 indicates a problem with the A.I.R. system. This code is a common indicator of an electric a.i.r. injector reactor problem. Sounds complex but it's not. There are two of these reactors on your engine. They are the black things that the secondary air pipe plugs into at the exhaust pipe/or/exhaust manifold. It is worth changing both of them becauses if one fails the other is not far behind. It is also worth replacing the factory hose clamp with a regular one---you'll see what I mean.BTW--P1415 specificaly indicates a problem with Bank 1 of the A.I.R. system. Make sure both sides of the A.I.R. system are in order--meaning all the hoses are tight and secure--no leaks--cracked hoses ETC.
