    Auto diagnostics software is a great modern tool that helps effectively identify current problems with your vehicle at an efficient rate. One of our technicians will scan your car’s onboard computer which will read any troubleshoot code your car may be experiencing. Your check engine light could mean several things involving your car’s engine, oil or transmission system including:

    • Air-fuel Metering
    • Emission Controls
    • Fuel Injector Malfunctions
    • Vehicle Speed Control & Idle Control
    • Ignition System Misfires
    • Computer Output Controls
    • Transmission Controls

  • Emissions Repair

    If you want to register your vehicle, it must pass an emissions test which checks for pollutant emissions that your car’s engine produces and ensures it is within regulations. Some states require these to be done annually.  If you fail your emissions test, Rob’s Discount Mufflers is here to make the necessary repairs it takes to get you to a passing grade. Some reasons for a failing score include:

  • • Faulty Fuel Metering
    • Defective Oxygen Sensor
    • Fault Spark Plugs

    • High CO2 Levels

  • • Defective Air Injection System
    • Faulty Evaporative Emission Control System
