2011 Escape, check engine light comes on
My check engine light came on a couple of weeks ago. Went to Advance and they read the codes which told me that I had a slight leak in the gas cap area. This system has no cap so we manipulated the flapper a bit and the light went out. I had the oil changed at the dealership on my 2011 Escape a week later. I drove less than a mile and the check engine light came on. Instead of paying Ford to put it on the machine I took it back to Advance and again it showed a a slight leak in the in the around the flapper where you insert the gas nozzle when filling up. When we got home my husband unhooked the ground to reset everything and viola! the light went out. It stayed out for a week and it is now on again. I could run back to Advance, but I know what the result will be. The car runs great, is getting very good mileage, and all appears to be super except for the check engine light. Any suggestions?
