Re: Code P0301
P0301 is misfire on cylinder #1.
Verify ignition components are in good condition.
Verify no oil down the spark plug tube.
Verify spark plug is not loose, worn, damaged, or incorrectly gapped.
Verify valves are correctly adjusted.
Verify EGR ports in runners are clean. If you have over 80K miles and the original cast plugs are still installed in the intake manifold runners then they are most likely getting plugged up.
You will need a slide hammer and replacement plugs 17199-PT3-AHM,

ATTS light will come on if it is disabled or in limp mode. Since no codes from the ATTS were stored, most likely it is on due to the engine code and the light will most likely clear after P0301 was been repaired.
