Im having a time finding the o2 sensor on my 1996 buick lesabre can you help me please could you please show me the diagram with the location where to find them

oxygen sensors ( O2S) are located after the cat converter/s
heated oxygen sensors (HO2S) are located in the exhaust manifold/s before the cat converters
so on a 4cyl/in line 6 cyl engine --1 of each
on a v6/v8 --2 of each

Hi Alvin,here's a link to a picture of your engine and your sensors,just click on the sensor and it will show you what it look's like. 3800 V6 Engine Sensor Locations Pictures and Diagrams

PWR WDO - 30amp circuit breaker , DRV -MDL 10amp fuse - both are located in the rear fuse box .
Fuse Block Rear
Under the left side of the rear passenger compartment seat

Sounds like the timing is too low - if it is electronic timing id check the computer with a code scanner - something not quite right tho... but you dont want to spend good money after bad but.... that can be a bottomless pit!

On this website you find fuse box diagram for Buick LaSabre (1997)

Hope this helps (remember to rate and comment this answer).

The O2 sensors are located on the exhaust system piping. Either on the manifolds or on the pipes themselves. You will need the vehicle cool, then disconnect the electrical connectors. Do them one at a time. You will need either a special O2 sensor socket or a 17 - 22 mm wrench to remove them. Unscrew them from the pipe and rescrew the new one back in. Then reattach the connectors. Then you can start the car.

Here is a picture of the alternator installed, hope this helps

the dual crankshaft position sensor is secured in an aluminum mounting bracket and bolted to the left side of the timing chain cover, partially behind the crankshaft balancer, hope this helps get back to me if you need mre help. please rate my fix as i strive to be the best

The belt tensioner is to the right below the alternator .
