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.
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.
The cost of a 1998 BMW M3 catalytic converter typically ranges from $500 to $1,500, depending on whether you choose an original equipment manufacturer (OEM) part or an aftermarket option. Prices can vary based on factors like location, the specific model variant, and whether installation is included. Additionally, purchasing used or refurbished catalytic converters may offer lower prices, but it's essential to ensure they meet emissions standards. Always check local regulations regarding catalytic converters when making a purchase.
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.
