I had the CEL come on but im not sure of the code they said it was running lean but could not find the problem.they said they checked my vaccum lines and my intake so the obvious things and charged me nothing they said they would need further diagnosis and that i should probably take it back to the dealer. but me and ford dealerships dont see eye to eye. they messed with my car before on a few ocassions so from now on i try to take it to my frenz shop or other reputable companies.
