P0301 says that the cylinder #1 is misfiring.
What need to be check is first of all the condition of the spark plug in that cylinder. Just describe me how it look like when you remove it.
Make sure any clamp athe manifold is tight enough and not loose.
Make sure the injector on that cylinder is not dirty, have the injectors clean at walmart.
Make sure the spark plug boot on #1 cylinder is not broken inside.
P0113, this code is about the intake air temperature,
the connector may be bad or the sensor is bad. It is located just after the air filter and it is squeezed in the big rubber boot from the air filter to the intake.
the MAF may be faulty or Check for loose tube clamps near the MAF sensor
P0316 this last code is a combination of all the code above.
Ask if you have questions.
