Thanks for your time and tenacity, we seem to have a lot in common.
I patiently await your prognosis and or fix directions

Answer
the 640 code is the cvvt solenoid ,probably bad unless it had a timing belt recently .clean throttle and have software upgraded ,replace ignition coil n04 and check the rest for cracks.maf 1300 could be fixed by cleaning throttle ,harsh reverse engagement could be real i see a torque code .code have a maf sensor problem also as this is a none turbo and air flow is built into the maf .hope some of this helps rob ..
