Sure sounds like a battery / alternator issue , take it to an autozone or checkers , let them test the battery and charging system as a courtesy , and a second opinion . thanks.

The engine runs rough and periodically stalls upon engagement, not while in P or N. Spark plugs, wires, ignition coils, and the module have all been replaced to no avail. Last week we took it to a mechanic...


Try unplugging the mass air flow sensor or tapping on it when it is running and listen for idle changes.The mass air flow sensor is located on top of the throttle body and is a rectangle held in place by tamper proof torx screws.If you unplug this the engine light will come on but if it stays running while driving then you can be pretty certain this is causing a problem.

My 2000 buick lesabre is stalling and cutting off while driving


suspect 'mass air flow' sensor or possibly a rip in the air duct from the air filter to the throttle body. this sensor, if bad, can definitely cause stalling/rough running and is notoriously difficult to diagnose, as an intermittent failure often does not throw a code to trip the chk engine lite. the sensor is located immediately next to the air filter box and has a connector of approx 6-8 wires going into it. one quick and dirty way to elicit a problem (if there is one) is to gently rap on the metal housing of the sensor w/ the handle of a screwdriver or a small light hammer. it is advised to avoid hitting the flat plastic part on the sensor (where the wire connector is inserted) since there is sensitive silicon circuitry underneath and you could potentially break something that may not have been broken already.

2000 Buick Lesabre: Driver Door 1. Do I have to disarm the air bags to replace glass? 2. How do I pry off the inside driver side door panel components? 3. HOw do I replace the inside driver side...


Hello, NO you don't have to disarm airbags for glass.
You can pry off the door panel with big flathead screw driver. The panel is held on by plastic tabs that pry off and you can press them back on with fingers.
Before prying off panel, you should pry off electric window button panel. Also remove any screws that are visible. Sometimes the arm rest has little plastic covers with screws underneath it.
This is actually easier than it sounds.
Just remove any visible screws, and pry it off and lift up and she'll come off.

sounds like a battery ground,check chassis ground strap coming from - batt terminal to the body. Also the one bellhousing bolt in front of engine down by the starter has ground for sensors.
Check there ,make sure it's tight.
