Went in for the free check engine light scan which is good. They told me that it had to do with the evap.I paid about $200 truck then worked fine about 3 weeks later the light came back on I took it to one of my customers to have it. Checked out he told me that it was the gas cap that didn't work anymore I showed him the work they did on my truck he said that it was not needed so I got jacked for $200 lesson learned no more going there
