2001 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.

The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.

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.

Keeps coming on and off not for sure if its the antenna or some thing else

The pcv valve may be located below the MAP sensor but the electrical connector & the MAP sensor seem stuck. I do not want to break them. Should I force it? Am I in the right place for a 2001 buick lasabre? How do I replace the pvc valve?
Thank you,

2001 Buick LeSabre Reviews

I have had my 2001 for 3 + years and I have 111K miles on it, the only flaw I have is the dashboarf has come loose and is bulging up in the center. makes it look terrible. done minimal maintenance above the regular PM ( oil changes) I liked the Buick (my first Buick ever) so well I bought a new 2009 lucern for my wife. we now have to geezermobuicks as the kids call them. my bext new car?--...

I absolutely love my LeSabre. It now has 195,000 miles. I did need to replace the tranny at 70K and the dash is now separating at the windshield, but I love the roominess, comfort and great gas mileage. I would buy another in a heartbeat if they still made them!
