now I am getting p0300 random misfire. I bought a Bluetooth obd2 connector paired with a torque app so I get a freeze frame:

Fuel Status = 0 byte
Engine Load = 4.706 %
Engine Coolant Temperature = 183.2 °F
Fuel Trim Bank 1 Short Term = 0 %
Fuel Trim Bank 1 Long Term = 11.719 %
Fuel Trim Bank 2 Short Term = 0 %
Fuel Trim Bank 2 Long Term = 7.031 %
Intake Manifold Pressure = 4.496 psi
Engine RPM = 1,290.5 rpm
Speed (OBD) = 9.942 mph
Mass Air Flow Rate = 12.6 g/s
Throttle Position(Manifold) = 12.549 %

What are the normal values?
