Mileage is 130k with automatic transmission and I’ve included pix of the Think OBD 100 readings.  I’ve cleaned the MAS sensor according to your video, waiting an hour before reinstalling.  All plugs have been checked for tightness.  The first 15 minutes the car operates fine.  After that it refuses to go into overdrive.  The codes PO 325, PO 440 and PO 446 indicate knock sensor and evap emission system and evap emission vent control circuit.  It appears to be running rich (upon startup it does smoke a little). I’ve checked for short in system according to your instructions and also disconnected the battery completely to reset the system. Reset does make the check engine light go away for a few minutes.  

Bought this from my sainted mother 5 years ago. She was the original buyer. Plan on keeping it a long time.   
Cant figure out how to send pictures! arrrgh
