The Check Engine light flashing is pretty much a universal sign that you have a misfire that is bad enough that a lot of raw, unburned fuel is being dumped into the Catalytic Converter, to the point that it could be ruined if the problem is not taken care of very quickly. If that happens, you're looking at usually a few hundred dollars, on top of whatever the original problem is. It's also, a fire risk, as the CC already gets very hot normally, but even hotter if overloaded.

The first thing I would recommend, is that you ask friends/family/co-workers if they know of a really good mechanic. Then, unless they're REALLY close by, have your car towed there. Or, if you insist on driving it, make sure you have a fire extinguisher handy.

Has the fuel filter been chg. lately. If it has, maybe a fuel pressure test is in order. Fuel pump might be geeting weak and does not show up until it gets warmed up. Fuel pumps are a common problem on this type of cars.

Most major Autoparts stores will get the Diagnostic codes from car computer and give you info on why light is on and what the problem is.

SOURCE: I have a 2000 buick lesabre. The fix engine soon

It NEVER was the camshaft sensor! Unless, you've removed the engine lately, which I doubt.
RUN to Advance Auto Parts and buy a can of "SeaFoam" and add to your gas tank per instructions...drive at least 100 miles and the problem should go away...IF it doesn't you'll have to replace the O2 sensors in the exhaust system...Any good mechanic should be able to do this for much less $$ than the dealership DO NOT go to the dealer for repairs!
Good Luck

2001 Buick Lesabre starts normal everyday. Car sits three days or more will not start unless you put the accelerator pedal down at least twice

put the accelerator pedal down at least twice ? While cranking the engine ? key on ? what ? Your vehicle has electronic fuel injection ,not a carburator . Pushing the gas pedal doesn't do anything The only thing if pushing the gas pedal to the foor an holding it there will put it into clear flood mode , shutting off the fuel injectors .

Buick lesabra 2001 dies while driving, voltage light comes on.

hello, you may need to have engine tuned up, have choke checked out, usually all the lights,bells and whistles will come on after it dies.because you are having to start engine again, when first starting engine, see what all lights comes on, then when engine dies it should be the same lights coming on when first starting engine, thats pretty normal ,have all filters checked out like gas filter, air filter etc

My 1990 Buick Lesabre shakes at 40 mph what do I do?

Check front engine mounts. Open hood, hold brake pedal down, put car in drive, press gas pedal down a little and see if engine jumps up due to a broken mount.
