Auto diagnostics software is a great modern tool that helps effectively identify current problems with your vehicle at an efficient rate.

Your check engine light could mean several things involving your car’s engine, oil or transmission system including:

  • Air-fuel Metering

  • Fuel Injector Malfunctions
  • Vehicle Speed Control & Idle Control
  • Ignition System Misfires
  • Computer Output Controls

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

  • Defective Air Injection System
  • Faulty Evaporative Emission Control System
