Answer 1

P0606 ECM / PCM processor fault.

This is a fault with the ECM. or internaly of the ECM such as poor connection. You may not have easy access to the ECM but access the the ECM and ightly tap on it to see if it acts up.

 This ECm had the same problem , having easy access we just tap on it and sure enough the engine would act up.
