A proper fuel system service cleans the injectors, intake and combustion chambers so the engine runs the way it should. Over tens of thousands of miles, carbon and varnish build up on fuel injectors, intake valves and throttle bodies. The result creeps up slowly, a rougher idle, a little hesitation off the line, a drop in fuel economy you blame on the gas. A professional **fuel system service** at TAB Motors clears that build-up and brings the engine back. As one customer told us after his service: "I could actually feel the difference." ## What a fuel system service does - Cleans fuel injectors so they spray in a fine, even pattern - Clears carbon from the throttle body and intake - Removes combustion-chamber deposits that cause knock - Restores smooth idle, crisp throttle response and MPG - Helps direct-injection engines that are prone to valve carbon ## Signs your fuel system needs attention If you're noticing a rough or surging idle, hesitation when you accelerate, harder cold starts, or a check engine light for a lean condition or misfire, the fuel system is a common culprit. We'll confirm with [engine diagnostics](./engine-diagnostics.html) before recommending anything, so you're only paying for a service you actually need. ## Part of smart maintenance A fuel system service pairs naturally with an [oil change](./oil-change.html) and a [tune-up](./timing-belt-ignition.html) with fresh spark plugs. Together they keep a higher-mileage engine running clean and efficient, often for far less than people expect. ## Frequently asked questions **How often should I get a fuel system service?** Roughly every 30,000 miles is a good guideline, or sooner if you're feeling rough idle, hesitation, or dropping fuel economy. **Will this really improve my gas mileage?** When deposits are the cause of lost MPG, yes, a clean fuel system lets the engine burn fuel efficiently again. We'll be honest if we think something else is going on. **Is fuel injector cleaner from the store the same thing?** A bottle in the tank helps a little for maintenance, but it can't match a professional service that cleans the injectors, intake and combustion chambers directly. **My check engine light is on, could it be the fuel system?** It can be. We'll scan the codes and diagnose the real cause before recommending a service. --- Call (703) 243-3080 or visit 4035 Old Dominion Dr, Arlington, VA 22207.
