Very difficult getting the gas cap off. I have to kind of pry it off with my fingers in back and forth sort of motion. Bought the car used about 1 1/2 yrs. ago, worked fine for a week or so. Have not fixed it but would give it a try myself if you have suggestions?!
Check engine light came on and I took the car to repair shop. Mechanic kept the car for one day and told me that he had identified the problem as an ill-fitting gas cap. He replaced the gas cap because he said that it was worn and not fitting tightly enough and he said that was causing the engine light to go on. That sounded like repair shop voodoo to my husband, but amazingly the new gas cap solved the problem.
