Where is bank 1 sensor 1 located on a 1998 Pontiac Bonneville 3.8 ?


If you have never replaced your O2 sensors it is well past time. The normal service life for O2 sensors is generally 60-75K. Your vehicle probably has a good 200K which means you should replace all of the oxygen sensors. These sensors are a major input to the engine management computer ...specifically providing info about fuel mixture. When the O2 sensors fail they provide bogus information; replace them all and you'll find your Bonny will run a *whole* lot better.

I have a 1998 pontiac bonneville se , engine 3800 (no turbo) the car idels smooth,but when you mash down on it , the car starts mising and than levels out , it also miss if you kick it the passing gea


I seriously doubt it.
The O2 sensors measure the amount of unburned fuel in the exhaust and would not be affected by water if you got them wet.
The spark plug wires and coils would be affected.

1999 Pontiac Bonneville 3800 engine. How do I replace the water thermostat?


Follow the top radiator hose down. It will connect to the engine. At the point that it connects to the engine is where the thermostat is located. This thermostat cover will have two bolts. Some of the 3800 engines have a temp sensor in the housing. You will not have to mess with the sensor. The housing will have 2 bolts that hold it on. Remove the two bolts and the housing will lift off. And the thermostat will be under the housing. Replace the thermostat. And reinstall the housing.

Where is the oxygen sensor located? heard it was on firewall...


Nope not on the firewall. The O2 sensor is located in the exhaust system. Start at the exhaust manifold and then the exhaust pipe down to the catalytic converter. You will find the Oxygen Sensor screwed in somewhere. It looks like this. 2f8606b.png
