Rich or Lean Fuel Mixture

Are you having a rich or lean emissions problem? Rich mixtures are caused by too much fuel or not enough air. Engines that run rich or lean will create excessive exhaust emissions. If the engine is starved for fuel (too lean), or getting flooded with fuel (too rich) it will fail to start and run properly, get poor fuel economy, will fail the emission test. The major pollutant produced by gas burning vehicles is carbon monoxide. If your vehicle is burning too much gasoline, which is called running rich, it will in return create an increase in this harmful gas which can cause the car to fail the emissions test.
