Hey guys new to the fourm and I just bought a 2010 fusion 2.5L with 74,000 miles it had a full tank when we bought it but now every time I get gas and only then when I start it up to pull away it surges and acts if it was misfiring then stalls but it will start right back up and run fine untill I refuel. Tonight It just threw a code I think it was a p2196 but it went away after about 30 miles. Any ideas or your thoughts would be great
