    Mass air sensor going out? Take it somewhere and have it plugged in for a diagnostic.

    Who did the tuning. I hear stories from hp tuners about how complex the idle is-you may have a vacuum leak or more likely just the tune. See what frost can do for you-you can send him logs of your car running and he can fix it for you accordingly.
