Why does my mini cooper have a gas smell but no leak?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! A gas smell with no visible leak and stuttering on acceleration is a classic Mini mystery. Odds are it’s a fuel vapor issue—probably the EVAP system, which handles fuel vapors. A loose or cracked gas cap, a faulty purge valve, or a leaky charcoal canister could all cause the smell. If the stutter’s in the mix, it might even be a misfire tied to a fuel delivery issue, like a bad injector or fuel pressure regulator. Get it checked soon, though—a persistent gas smell isn’t just unpleasant; it can be dangerous.
