    Take it right back to them and have the shop fix it to a drivable condition? Any of those symptoms there before the shop got their mitts on it?

    Check or clean your MAF sensor as well. If you have drivability issues with no check engine lights, then most likely your MAF is dirty. I had my radiator replaced a few months ago and when I left my tuner, my car would buck under throttle. I turned around and went back and they found a low MAF code on their scanner. They took out my MAF and cleaned it. Took it for a test drive and to this day all is good.
