Considering that currently there is an additional Federal warranty on emission equipment including the catalytic converter, it is prudent to seek advice in the dealer's service department before making a replacement. The element that stands out in this case is the catalytic converter; it is an emission control part of an automobile exhaust system aimed at minimizing polluting substance in gaseous effluents. It has Single-bed converter along with Three way catalytic converter that comes with the catalytic coat of platinum and Rhodium and it helps to reduce the content of oxides of nitrogen, Hydrocarbons, and Carbon monoxide present in the exhaust. Equipment for testing catalytic converters is quite expensive and technical; if one has a feeling that his machine is affected, it is advised that he or she should go to the dealer or an emulsion inspection station. When the underbody components are serviced, it is necessary to look at the converter for signs of leakage or rust, dents and other forms of damages, check the welds and flange bolts holding the converter onto the exhaust system. Catalytic converters are normally very resistant; however, they do become plugged. For a restricted converter, what would be the trick to determine is the effect of a blocked exhaust on the intake vacuum where a vacuum gauge is best suited for the task. This is done by linking the gauge to an inlet manifold vacuum source, then warming the engine, and observing the vacuum value while the engine idles, with opening the throttle to around 2000 rpm, then swiftly releasing it, and noting the vacuum multiple times. Many car owners often experience this type of deviation which is Reading after Warm-up being more than one in-Hg lower than the Idle Reading This is most likely caused by a plugged or restricted catalytic converter, muffler, or exhaust pipes.
