Definatly clean you're maf, if you were without a filter for 6 days there is a high chance of it being somewhat dirty. I also can suggest you clean you're IAC valve. Doesnt cost anything and only takes about 30 minutes of you're time. Once completed with both of these tasks, reset thwe computer, start, then let idle in driveway for about 5 to 10 minutes while the computer relearns everything again.
