I have just changed the spark plugs. My truck runs great. But I have a fuel smell that comes and gose. I thought I might have move a fuel injector and there are no signs of a leak ( I never took the fuel rail off). I have took each coil pack off and smelled the end of each pack (no gas smell). I made sure all plus are tight. Every thing is dry. I smell it strong in the A/C vents sometimes. But when I pop the hood there is no smell around the eng. What do you think?
