The problem is the crankshaft sensor for sure. It is mounted behind the crankshaft pulley which is pretty difficult to get off as you need a special puller. A shop should charge about 1.5 hours for this job. It is a very common problem.

SOURCE: how to install throttle position sensor 94 buick

locate the throttle body and on the side match your new T.P.S sensor, its usually held on by 2 screws, torx kind, so you might have to buy that screw driver since it is not common. remove and disconnect the old one and install. if its adjustable you need to set it, with a voltmeter. if its not just make sure it engages and slides in fine.

How reset the security feature on 1998 buick lesabre

Unfortunately there is not a reset feature. You will either need to install a new lock tumbler with key sensor, or install the correct resistor in the harness to bypass the key sensor.

Sputtering Engin on 2000 Buick Lesabre

O2 Sensors only reads Oxygen Content in Exhaust
Converter,so forget that persons advice in the future

The O2 Sensor info is for adjusting fuel trim or injector
pulse timing,not your problem

You change front upstream O2 sensors at 100,000
miles, as preventative maintenance

Check Fuel Pressure at motor & pump maybe failing
as well,doesn't hold pressure thus takes too long to start

Clean the Air Idle Valve on throttle body & it won't shut off
at stops

1998 lesabre check engine light oxygen sensor bank 1 sensor 2.Wher is it located?

Just because you have a check light on & a code,does not mean
the O2 Sensor is bad.

Bank #1 is always on the side that cylinder #1 is on
Sensor #1 is closest to the engine before in in the converter
Sensor #2 is the Rear,Downstream or Monitor Sensor
usually in the converter outlet

Just want you to be aware that when you replace it you may still have
the same check light & code & then mabe you wil get lucky

That way of doing things will only work a couple of times

Most GM motors, the #1cyl would be on the motors left side
On a Ford, the front right side

If you have single exhaust it is easy & you may as well do both
O2 sensors

The upstream or front one gets done every 80 to 100,000 miles

The rear ones SELDOM FAIL that is why I'am explaining all this

How to change o2 sensors in a 1993 buick lesabre

The o2 sensor is in the rear exhaust manifold.You should be able to see it from under the hood.It takes a 7/8 special socket.You can find you at any parts store.You might want to soak it with penetrant.P.B.blaster works real good.Try not to cross thread it.There is only one o2 sensor on your vehicle.Hope this helps.Good luck.

How to change oxygen sensors in 92 buick lesabre

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.
