Symptoms of a bad catalytic converter in a Dodge Dakota, or any vehicle, include exhaust issues and poor performance. Drivers also notice an offensive smell coming from the vehicle, similar to rotten eggs or sulfur.
If the Dodge Dakota is producing dark or black exhaust from the muffler, it indicates that the catalytic converter is faulty. This also indicates a lot of carbon buildup in the engine. If a car is well taken care of, such as with regular maintenance and good fuel, the culprit is likely the catalytic converter.
Another symptom of a faulty catalytic converter is less efficient performance. One thing that occurs is the inability to drive the car at a normal speed even when the car is given a lot of gas. A driver may also notice a lot of jumping or jerking with no explanation when accelerating. The most tell-tale sign that a Dodge Dakota needs a new catalytic converter is the scent of sulfur and rotten eggs. The smell is difficult not to notice, and it almost always indicates the need for a new catalytic converter.
If a new catalytic converter is needed, the average cost ranges from about $500 to $900, as of 2015. Almost $300 of this cost is due to labor.
