You know me, I'm only in Georgia for a month or so so it is difficult to work on the car. I did put a scanner on the car and it said problem with the map sensor which I kind of thought it might be so I ordered a new sensor and will try that when I get back next April. If that doesn't do it I will reach out to you for your tuners name.
Here's a link to my friend: http://www.suja1motoring.com/
In case, you feel like looking into him or just contacting him to chat (let him know I sent you).
I've been friends with him since the mid-2000s and have driven up to him in Chicago just to get my car tuned, in the past.
But fortunately, he's a little closer now.
p.s. If I find some time, I could potentially go up and help you fix it/work on it before your April return.
