The computer codes are P0171 and P0174 setting the engines fuel system to lean out. The 02 sensors seem to be fine.When the car is driven theres a slight hesitation at the hit of the gas petal and at full throtle in 3rd-5th gear,and the engine pings when its hot and under a load.

confirm if there is a leak where the intake manifold and cylinder head meet between each intake runner.
