i would start by removing the mods and putting the car back to factory condition with factory tune and see if your problems are still there.

Start with one code at a time and diagnose from there.

Sometimes multiple DTC’s could be tied to others if the failure is associated to an initial code.

There have been TSB’s for misfires associated with the IMRCs and VCTs - you’ll have to narrow down your codes to see if either system is causing the faults.
