Buick LeSabre Problems
It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.
One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

Slamming on the brake did not change, but after a few seconds the oil prussue would return to "normal" which is a stagger 130lb, which as been since new. I was wondering if this is an oil sending unit or a computer, or a oil pump, How do...
when I turn my car off and take out the key , open the door and the warning sound is letting me know my lights are still on. the brake lights and parking lights will not turn off. all other lights go out but not the parking lights or brake lights. does anyone have any suggestions?
My 2001 lesbre has been one of the best car I've bought in a while the only problem I've had since day one was the fuel gauge bounce from empty to full which I took care of by replacing the fuel sender I bought from eBay for 27 dollars and it took me about 20 minutes to replace other than that I have no complaints
