Question about 2004 Kia Sorento

1 Answer

My KIA 2004 Sorento jeep was emiting a whistling sound on throtling and had very low power. The check engine light is on. It was discovered that the converters at the exhaust maifold are hollowed and the exhaust system was blocked. Another bigger catalyst converter distal to the ones at the manifold was blocked. This blocked or plugged converter was replaced with a good one and the vehicle is now okay but with the check engine indicator still on. But my question is, what will now be the general performance of my vehicle as I was not able to replace the catalyst in the converter at the manifold? Will it affect my gas mileage so much or ...? (Remember the converter at the manifold is now hollow and the sensor wires intact)

YES, the emissions will be effected, you are driving "without" a converter. The computer was programmed to have all sensors work together so the emissions run clean. The oxygen sensors are sending signals to the pc about unclean emissions due to that converter.

SOURCE: Two of the catalytic converters of my kia sorento jeep get red hot. My check enging light is always glowing while driving. The vehicle emits a whistling sound on throtling and the vehicle power is ver

If you scan the error codes what does it say? You can get this done at any autoparts store (chain) for free. However it sounds to me like there is some air restriction in the intake that is causing the loss of power and the exhuast is running rich. This causes the catalytic converter to overheat. You need to be mindful that any leaks of fluid near the catalytic converter can cause a fire and the loss of the entire vehicle when they get this hot.

I'm not certain on the newer vehicles like this but this was a common problem on the older cars when the catalytic converter got clogged. Sometimes due to age and wear the converters would build up n just get stuck. If so, you may need to have them replaced at a muffler shop.
