Question

My car vibrates and struggles on 1 and 2 gear (automatic trans) what could be causing this. The following codes show up

p0430
p0660
p0113
p2078
p2017
p0123

Answer 1

P0430 Catalytic efficiency bank 2

P0660 Maniflod tuning valve (MVT) control circuit

P0113 Intake air temperature sensor 1 circuit high

P2078 Intake manifold tuning valve position sensor circuit high

P2017 Short runner valve (SRV) position sensor circuit high

P0123 TPS/APP circuit high (throttle postion sensor) (Accelerator pedal position)

Anytime you get a code that is circuit high this mean you have a harness disconnection, When a harness or power supply to a sensor is disconnected , you will recieve a circuit high code, Also check the fuses,
