Hello, my name is***** vehicle seems to run fine then it is probably a emission related problem such as a loose gas cap. But before replacing any parts you will want to start by having diagnostic codes checked which can be done at your local parts store for free. You can write down codes and reply to this answer at any time without additional fees. With the codes I can give you common/possible problems, testing/repair instructions, and costs. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
