Have your car in for an emissions test. It is a normal procedure today typically on an annual or biannual basis. Certainly it’s something that causes people a lot of concern and most of all, having their vehicle pass emissions. The advice that we could give as far as getting a vehicle to pass emissions is that first off we have to have a vehicle that’s running well. So taking care of maintenance items such as tuneup components like spark plugs, ignition wires and filters such as air filters and fuel filters and PCV valve is all an important part of that. Assuming that that’s okay and we have a good running vehicle and the check engine light is not on, then other possible reasons for failing emissions can have to do with things that are degraded and not necessarily bad. For instance, fuel injectors, as time goes on, become a little bit clogged and their spray pattern instead of putting out a mist will tend to put out a simple single stream of fuel, which doesn’t burn as well as the midst does other components that can become degraded over time.
Our oxygen sensors and catalytic convertersIn my opinion, these two components probably have the worst job in the entire automobile because they have to live in the exhaust and have a tendency to become coated with carbon. As time goes past the oxygen sensors, a sensor element is inside of this thimble and as it becomes coated with carbon, it’s signal can be delayed. Because of that, a catalytic converter whose job is to oxidize, basically on burn fuel or partially burned fuel and also to reduce oxides of nitrogen shares the same malady. It can degrade its operation, it could work not quite as well for reasons of carbon coding the actual catalyst material itself. And so that’s where, some components like having your fuel injection system cleaned or for that matter, using products that can clean out the system, can actually go through the cylinders, through the fuel injectors, cleaning out the nozzle of the fuel injector, actually helping to reduce the carbon build up inside of the catalytic converter and the carbon build up on the oxygen sensor. We’re restoring these things too close to their original operating condition and helping you to maintain low emissions, which should help you pass the test.
