P2238 and p0300 only under hard acceleration. When i restart the car its gone. And drives normal. It also hesitates like hell

 

When was the last time you replace your sparkplugs, and were they oem or original denso plugs and not fake plugs? If not recently I would check or replace all the plugs with iridum denso. What about the maf sensor, have you cleaned it? Also throttle body have you cleaned that? I checked the air filter, the tube from the air filter to the throttle body, make sure theres no air leaks in between
