It has to be something related to the variable camshaft system. I noted you are a beginner mechanic. I almost feel bad doing this, but I will provide a pinpoint test diagnostic procedure. It is extensive, but you may find the issue prior to going through everything.

HK16 CONTINUOUS DTCS P0011, P0012, P0016, P0018, P0021 OR P0022: CHECK THE OPERATION OF THE VCT SYSTEM
Note: Some vehicles require higher RPMs and loads to actuate the VCT system than others. The VCTADVERR PID should be close to zero whether actuating or not. During rapid VCT movements, the VCTADVERR PID may momentarily deviate from zero. In addition, normal deviation may momentarily move to the end of the scale on a rapid acceleration.
Note: For a symptom based concern, monitor all applicable PIDs during this step.
- For DTCs P0011, P0012 or P0016.
- Access the PCM and monitor the VCTADV (ANGL) and VCTADVERR (ANGL) PIDs.
- For DTCs P0018, P0021 or P0022.
- Access the PCM and monitor the VCTADV2 (ANGL) and VCTADVERR2 (ANGL) PIDs.
- Drive the vehicle while exercising the throttle to generate VCT movement.
Does the VCTADV PID indicate VCT movement while the VCTADVERR PID maintain close to zero?
Yes
- Unable to duplicate or identify the concern at this time.
No
- If the engine runs rough at idle and KOER or Continuous Memory DTCs are present: GO to HK18.
- For all others, GO to HK17.

HK20 CHECK FOR CORRECT PCM OPERATION
- Disconnect all the PCM connectors.
- Visually inspect for:
- pushed out pins
- corrosion
- Connect all the PCM connectors and make sure they seat correctly.
- Carry out the PCM self-test and verify the concern is still present.
Is the concern still present?
Yes
