Yes, C&C Automotive advises that a clogged catalytic converter can cause poor engine performance. The reason why is that the exhaust gets stuck behind the catalytic converter and flows back into the combustion chamber. When this happens, the engine combustion is compromised, and, as such, the engine’s performance and acceleration will sputter and lag. Head straight to our shop so we can inspect the catalytic converter and replace it if necessary. Here are other signs your catalytic converter is bad.
Reduction in Fuel Economy
The compromised engine performance will also reduce your vehicle’s fuel economy. This is because the engine will use extra fuel in an effort to produce the power you desire from it. Unfortunately, you will continue to get bad gas mileage until the underlying problem, the poor engine performance, is resolved. Replacing the clogged catalytic converter will resolve the issue.
Black Engine Exhaust Smoke
If you see black exhaust smoke flowing out of your tailpipe, this, too, could be a sign that the catalytic converter is clogged. When the converter is clogged, it malfunctions. A malfunctioning catalytic converter cannot treat the engine exhaust. This leaves the exhaust filled with hydrocarbons that make it black. The black exhaust smoke is also a result of the excess fuel burn.
Exhaust That Smells Rancid
If your vehicle’s exhaust smells rancid, the catalytic converter may be clogged with sulfur deposits. Any time the scorching exhaust flows over these deposits they release a smell that is a lot like rotten eggs. Rancid exhaust odors are definitely a sign that your catalytic converter needs to be replaced. Bring your vehicle to our shop as soon as possible.
Heat Under the Vehicle
One reason why time is of the essence is that the catalytic converter will start to produce too much heat as it malfunctions. Unfortunately, this heat can rise up into the engine and cause your engine to overheat all the time. This can make driving your automobile damaging to the engine.
Check Engine Warning Light
Finally, all of the above signs may cause the engine control module to turn on the check engine light. Because the catalytic converter does not have a light of its own the module uses the check engine light to warn you of trouble.
