Slow RPM gain and rough idle, cylinders 2, 4, 6 not getting power

I would recommend you look at the oil control valve on the driver intake side. Attached diagrams below. If the solenoid is faulty or your low on oil it will cause timing issues and misfires.

SYSTEM DESCRIPTION

System Description

Open In New TabZoom/Print

This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake valve.

The ECM receives signals such as crankshaft position,  camshaft position, engine speed, and engine coolant temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing control solenoid valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to increase engine torque in low/mid speed range and output in high-speed range.

IVT CONTROLÂ SOLENOID VALVE

Component Description

Open In New TabZoom/Print

Intake valve timing control solenoid valve is activated by ON/OFF pulse duty (ratio) signals from the ECM.

The intake valve timing control solenoid valve changes the oil amount and direction of flow through intake valve timing control unit or stops oil flow.

The longer pulse width advances valve angle. The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve stops oil pressure flow to fix the intake valve angle at the control position.

If the variable valve timing is not doing what is suppose to then it will effect that one bank. As for the other lights, you need to have a volt meter to properly check the voltage.
