What Is That Awful Smell in My Car’s Exhaust?

If your car, truck, or utility vehicle has an awful smell in the exhaust that reminds you of rotten eggs, the catalytic converter is going bad. Tri Valley Auto Repair & Diesel can inspect your catalytic converter to see if it is clogged. This is the most common problem catalytic converters face. If it is clogged, we can replace it so that you no longer smell rotten eggs in the exhaust. This unpleasant odor is just one sign of catalytic converter problems. Here are other signs.

Black Exhaust Smoke

The catalytic converter treats the engine’s exhaust to make sure it is safe to be released into the environment. If you see black smoke coming out of the tailpipe, this is an indication that the catalytic converter is not treating the exhaust. It can also be a sign that there is too much fuel in the engine, and the excess fuel is being burned away.

Sluggish Engine

A clogged catalytic converter will create engine performance problems because the exhaust is not exiting the combustion chamber. Rather, it remains in the chamber and hinders fresh air and fuel ignition. This affects your engine’s ability to produce combustion, and, consequently, you will end up with sluggish acceleration and engine performance.

Poor Fuel Economy

Naturally, anytime your engine is not performing as it should be, it will burn through the gasoline or diesel fuel more quickly. Consequently, you will not get the miles per gallon that you normally get when you drive your automobile. Replacing the faulty catalytic converter can restore your engine’s performance and efficiency. This will also restore the fuel economy.

Extreme Undercarriage Heat

Your vehicle may get very hot underneath if the catalytic converter is going bad. You will be able to feel the heat underneath your automobile and it may cause your engine to overheat. Heat rises, so the excess heat being generated by the catalytic converter can create overheating problems every time you drive your automobile.

Dashboard Warning

Finally, your vehicle’s dashboard may warn you that the catalytic converter is going bad. For example, if the check engine light comes on and you are experiencing any of the other problems listed above, the check engine light is telling you that the catalytic converter is malfunctioning. This is our indication that we need to replace your catalytic converter.
