OK
One more quick thing I would like you to do..

After you get the code 13, I want you to clear it, run the engine after clearing and then turn it off.. Now, go back to same pin [8]and you should get a Single Flash [ code 1] . meaning code is clear..after the single code, wait 2 sec., hold button 6 secs , turn off key for 10 secs on for 50 secs and restart..That will reset the Memory and base line of the HFM module
Take the car for a couple of drives and see what happens..
I still suspect a vac leak [ mat be purge valve] , but do this first, as it a simple thing to do.
