Default P1639 code

ÇIt started after I installed an audio sound system. I ran the wire through the conduit behind the pcm. I turned on the car and it worked fine, I got distracted and my battery died so I had to push start it and on that cruise
it started to flash the service engine soon.

i connected the sCanner and it read p1639 and ftp I changed the ftp and the pcm at this point
the EVAP.
no differencedum
Running way to rich..
any ideas??
