Pontiac Torrent Misfire after head gasket replacement

I have a 2007 Pontiac Torrent with ~90,000 miles. I had to have the head gasket replaced about 2 months ago. Since then the engine has hesitation while acceleration. It has been in the shop 2 times now trying to fix it. I have had the Ignition coil replaced and the EGR valve replaced. Now it is still happening and was wondering if anyone had any suggestions.
