You bet, probably two.
No, it is illegal to remove a converter and besides the engine will not run correctly with the converter removed.
The O2 sensor is in the exhaust pipe before the catalytic converter.
check the catalytic converter. if the engine isisnt running hotter than normal it is most likely plugged exhaust somewhere likely in the catalytic converter
On a 2004 BMW X3, the oxygen (O2) sensors are typically located in two main areas: one before the catalytic converter (upstream sensor) and another after the catalytic converter (downstream sensor). The upstream sensor is usually found on the exhaust manifold or just before the exhaust pipe enters the catalytic converter, while the downstream sensor is located after the catalytic converter. Accessing these sensors may require lifting the vehicle and working under it, depending on the configuration.
The best way to improve fuel economy it make sure your tire are inflated to the factory specification (there should be a tire information placard on one of the doors). Beyond that, making the engine breath better will also have marginal benefits. You can try installing a less restrictive air intake system, and an exhaust system with wider pipes. If you live in a state or country that does not do emissions testing, then you can remove the catalytic converter(s), which are a huge restriction. If your car has to go through emissions testing, then there are hi-flow converters that may work. The above answer is correct except the part about removing the catalytic converter. First of all removing the catalytic converter is illegal. Secondly modern engines equipped with fuel management systems will not run properly with the catalytic converter removed. Do not, remove your catalytic converter.
On a 1998 BMW 528i, the O2 (oxygen) sensors are located in two places: one is upstream (pre-catalytic converter) and the other is downstream (post-catalytic converter). The upstream sensor is typically found in the exhaust manifold or just before the catalytic converter, while the downstream sensor is located after the catalytic converter in the exhaust system. To access them, you may need to lift the vehicle and work from underneath or remove some engine covers. Always ensure the engine is cool before attempting any maintenance.
The rear oxygen sensors are located after the catalytic converter's Usually under the vehicles floorboard.
Air/Fuel mixture too rich, cylinder misfire, or external damage to the converter.
I had a similar problem with a 1987 Cavalier, it turned out to be a bad catalytic converter.
well first you have to check and make sure your canooter valve ain't clogged, then u took the old one out and put the new one in....
A typical BMW catalytic converter contains about 3 to 7 grams of platinum, although this can vary depending on the model and year of the vehicle. In addition to platinum, these converters often contain palladium and rhodium, which also help in reducing emissions. The exact amount of platinum can differ based on the engine type and emissions regulations.
