Frequently Asked Questions About Auto Diagnostics

  • How often should I have my fuel system serviced?

    For most Denver drivers, we recommend fuel system service every 30,000 miles or 3 years. However, if you drive in stop-and-go traffic, dusty conditions, or use lower-quality fuels, more frequent service may be beneficial. Our technicians can recommend the ideal interval for your specific vehicle and driving habits.

  • How long does a fuel system service take?

    A standard fuel system service at our Denver shop typically takes 1-2 hours, depending on the extent of cleaning needed and any additional repairs required. We strive to get you back on Denver's roads as quickly as possible without compromising quality.

  • Will a fuel system service improve my gas mileage?

    Yes! Many Denver customers experience a 5-10% improvement in fuel economy after a comprehensive fuel system cleaning, especially if it's been some time since the last service. This improvement often offsets the cost of the service over time.

  • Is fuel system service necessary if I use premium fuel or fuel additives?

    Even with premium fuel and additives, deposits can still form in your fuel system over time. While high-quality fuels may slow this process, professional cleaning is still recommended for optimal performance, especially for vehicles driven in Denver's diverse conditions.

  • Can fuel system service resolve a check engine light?

    If your check engine light is related to fuel delivery or combustion issues, a professional fuel system cleaning may resolve the problem. Our diagnostics will determine if fuel system service will address the specific issue triggering your warning light.

  • What's the difference between using fuel additives and professional service?

    Over-the-counter fuel additives provide minimal cleaning compared to our professional equipment and solutions. Our service thoroughly cleans injectors, intake valves, and combustion chambers with specialized equipment that reaches areas additives cannot.

  • Does Importsports work on direct injection fuel systems?

    Absolutely! Our ASE Certified technicians are trained to service both traditional port fuel injection and modern direct injection systems found in newer vehicles. Direct injection systems are particularly prone to intake valve deposits and require specialized cleaning procedures.

  • Can fuel system problems damage other engine components?

    Yes, neglected fuel system issues can lead to damaged oxygen sensors, catalytic converters, and even internal engine damage. Early intervention with professional service helps prevent these costly repairs.

  • Do you provide fuel system service for diesel vehicles?
