How to change oxygen sensor on Acura 1999 TL - 1999 Acura TL

sensor 2 is always downstream of the Cat.

Which 02 sensor is bank 1 sensor 2? Bank 1 Sensor 1 is the first sensor closest to the engine. On Bank 1 means it is at the engine side with cylinders 1, 3, 5, 7, etc. Bank 1 Sensor 2 is the second sensor on the engine's exhaust pipe, usually behind the catalytic converter.

Throttle position sensor or a vacume leak.

You need to get to a repair shop and have them read the diagnostic codes (the computer port is in the center console under the change holder/lighter). With that amount of mileage, it is very likely the code will show that the oxygen sensors and/or catalytic converters need replacement. If that is the case you will also need a tuneup (plug, wires, etc). I had this done a year ago at 160,000 miles. It is a pricey repair but I get 29mpg at highway speeds and it runs nicely on regular (less power but no pinging).

you need to run the car and see if the fan comes on if it does change the thermostat and gasket if it does not you need a fan sensor
