Buick - Lesabre :: 2000 Shimmy While Accelerating Between 45 And 50 Mph
Jul 22, 2013
I have been to a few different repair shops for my 2000 Buick Le Sabre shimmy problem with no luck. I have a really bad shimmy, while accelerating between 45 and 50 mph, and it seems worse on an upgrade. Past 50 mph, it smooths out. Over the past several months, mechanics have checked the balance of my tires and rotated them, done front end alignment, rear alignment, replaced the right lower control arm, the right sway bar link and the right wheel hub. Still no luck, so it came down to the determination that it must be a bad tire. Now I have 4 new tires (it was soon time to get them anyway), and I still have the shimmy. What else can we look for? My local mechanics seems stumped. I have not taken it to a Buick dealership, however...

I have a 2000 buick lesabre v6 3800 series 2 engine and every now and then when accelerating it will miss out, I don't know what it could be?

Back in April, I posted this comment about occasional skipping when accelerating: "I have a 2003 Buick LeSabre with 187,000 miles (mostly highway) that skips/jerks sometimes when accelerating, even when in cruise control. It only does this every month or so; and, of course, never does it when the mechanic is in the car. No warning lights have ever appeared and my mechanic says no codes have shown up in three diagnostic tests.
In the last 1.5 years, the following items have been replaced: power steering rack, oil pressure sensor, FE control arm bushing, intake manifold gasket, oil pan gasket, transmission mount, water pump, rear struts. In 2010, an alternator, thermostat, mass air flow sensor and front brake pads were installed. Oil is changed as scheduled; tires are rotated as required and car is serviced at the first sign of any problem. Other than occasional skipping, car is in pristine condition and rides like a charm. The most recent skipping occurred March 29th when I was 200 miles from home. It lasted sporadically for about 10 miles and did not occur in the other 190 miles."
Based on the advice of responders, I had the fuel filter replaced and the car never skipped again ... until today, three days after the rotors and brakes were replaced. Like before, there have been no warning lights and the skip, which can occur when braking or when in motion, occurs sporadically. It might happen several times in a mile and then not happen again for some time. The car now has 192,000 miles. Is this the transmission, a problem with the recent brake installation or something else?

I have a 00 buick lesabre that I am having problem with no turn signals. It first started with the infamous fast blinker on drivers side, so i replaced all the bulbs , so when that did not fix the problem, i thought it was the socket, but it turned out ok, so i replaced the flasher and after that, I have no blinks at all, haz work but no blinkers. i tryed old flasher but still no blinkers. i checked the fuse that runs the blinkers, it was ok. I replaced it anyway.

I have a 2000 Buick Le Sabre and the car shakes when I step on the gas about 356mph and up. The steering wheel doesn't shake at all. I had my tires re-balanced twice but didn't work. Now a mechanic is telling me it might be the axle rod. How much will this cost? and is it a big job?

My Buick has started acting weird and I've had a hard time figuring out what's going on. As I understand it 94' was the transition year for the OBD1 and OBD2 sensors, therefore auto zone and o'reilly haven't been able to pull codes on my car. It runs off of OBD1 codes but has 16 point OBD2 sensor pins.
Here's the problem: When the car is started it revs up to 2000rpm at idle, when shifted into neutral the rpm jumps up to 3500. In drive and reverse it goes back down to 2000rpm. While driving the car is hard to stop and surges when I take my foot off the break, it also gains speed on flat ground without touching the gas pedal. After driving the car when I put it back in park it revs back up to 3500rpm and is quite noisy.
I've replaced the mass airflow sensor, cleaned out the entire throttle body (there was a little carbon build up but not too bad), replaced all the vacuum hoses(that put a stop to it for about a week), and I'm still having the same problems. I recently replaced the a/c pump because the bearings went bad but I don't think that would cause any problems like this.
I have a very, very slight gasket leak on my valve covers but it's been like that for the last few months and the car was acting fine. The car has done this before but it usually stops after you drive it somewhere. The hotter it's gotten out the more often it started happening and now it's not stopping like it did before.

I have a problem in the form of a 2000 Buick LeSabre Custom with the GM 3800 series II engine. After 245k miles, it has begun to show it's age in some very unaffectionate ways. It has been stalling, sputtering, hesitating, and unwilling to start at seemingly random intervals. And, such is my luck, there has been no 'check engine' light on at any point during this saga. Here's the chronology of events spanning 6 months:
The first symptom I experienced was occasional sputtering, mainly while going uphill. This began to occur shortly after the spark plugs were replaced during regular maintenance. So I replaced the spark plugs again, and also the wires, fuel filter, and fuel pressure regulator. Plus I gave the MAF a good cleaning.
But the problem persisted, and grew to include intermittent stalling when I would come to a stop. Undaunted, I replaced the ignition coils, and swapped in a used ICM.
The car, obviously displeased with my choice words toward it, began to not start every now and then. It would just crank to no avail. So I would try again after an hour or two and it would immediately start as if nothing was wrong. Fearing that I or my wife could be left stranded I replaced the fuel pump. It continues to stall every once in a while and it still sometimes sputters at low rpms. A lot of times it just wont idle at a constant speed.
So then I replaced the crank sensor and I cleaned the camshaft sensor too. Guess what? It's still intermittently sputtering/hesitating when I accelerate from a stop. And I have noticed that it will also sputter while idling in park as well. It's like it's misfiring, but with no engine codes. I'm not happy.

I have recently been having some movement in the rear of my car...I can mainly feel it when I am going under 20 mph. I have had replaced the two rear tires with other used tires cuz my original tires were going bald. Can this be the problem? Can Broken belts on the tires or "BAD TIRES" can cause this or is it another problem I should be worried about i.e sway bar links/ sway bar, etc.? 2000 buick PA 3.8

Vibrating at 50-55mph, also at 75+, was reduced considerably when forward transmission mount was replaced. Still shimmies and feel little in the steering wheel. Have replaced tie rod ends, back struts and tires. Need to figure out what I am missing.

I have recently noticed that my car will stall out when I get up to about 20 mph. My car starts fine, no check engine light on. I has a tendency to just die in the middle of the road at times too. I have changed the spark plugs, spark plug wires, and a new fuel filter. Do I need to change the mass air flow sensor? Or the crank position sensor? I have no problems starting the car either. Runs good when it runs.

1996 buick lesabre custom 3800. The car stalls from time to time, and the fuel pump, power windows, power seats, and power mirrors all stop working. Most people who have had this problem cleaned the ground bus on the drivers side under the carpet. I have done this, and the car has not stalled yet, but I haven't driven it far because I have noticed the fuel pump relay and power windows relay are getting extremely hot to the touch after 5 minutes or so of driving. Why these relays are getting so hot? I cannot afford to keep getting the car towed home.

My 2001 Buick Lesabre has always shown to run exactly normal on the temperature dash unit until recently. I checked my coolant level and it was a bit low, so I added. After I filled the radiator I have noticed a coolant leak spot on my driveway, after I drive it now. I have removed the gravel shield and have tried to pin point exactly where the leak is coming from, but cannot. Now, each time I park, after driving it, I put a clean piece of cardboard under it to try to see exactly what area the leak is coming from. Last night I put the car on ramps and crawled under to discover that the leak is located just above the oil filter and is actually dripping from the oil filter, but I still cannot see the exact location of the leak.Actually the leak does not appear until about an hour after I park the car, so it sounds like something is contracting after the engine has cooled off, but what? The leak has seemed to be getting worse each time I drive the car. How can I determine exactly where the leak is coming from without just changing a bunch of parts.

I currently have no brake fluid in my car because it keeps leaking out (leaks while actively being used). The leak is between the power brake booster and the brake master cylinder... Is there any type of gasket I can get to better fill the gap between the two pieces of metal? Is there some way to tell which of the two pieces is creating the leak to narrow down which to purchase?

My car would not start yesterday, and I realized the fuel pump was not running. So I bought a new fuel pump today and put it on, the car still won't start, the fuel pump still does not run and I have been told to check the relay. I cannot find the relay for this car.

My '98 Buick's AC works well when I take it to a mechanic. But when I leave after they say, 'it seems fine now,' a few miles later the cold air starts blowing through the defroster vents, still nice and cold. Then it comes back down to the dash and then goes back up to the defrost. But sometimes it stops blowing altogether, it doesn't blow anywhere! Nothing, not even warm air. And then later everything is fine again, until it happens all over again and I take it to another shop when I hear 'it seems fine now.'.

Driving my car over the week-end and experienced a lot of hesitation when I stepped on the gas. The car seemed to delay in kicking in to the next gear.I stopped and checked my transmission oil and realized I didn't have much transmission fluid, practically none. So, I added a quart. My question is what should I do now. I know it probably doesn't have enough but I don't know how much to put in. Or should I just have it changed?

I have a 2002 Buick LeSabre. Back information is this. the car has had a coolant leak for years, very slow though. Last night while working (I drive for a living) the thermostat climbed up to hot and then immediately went back down to the middle range where it normally goes, so I thought I was fine. It then climbed back up and staled out. It started again nearly immediately and I made it back to my work. About 30 minutes later I began to drive home. The temperature gauge started to climb up again, and then immediately went back to normal running temperature. I kept an eye on it.
About 2 minutes later it shut off completely. I had dash lights, head lights, and emergency flashers. Trying to restart it killed my battery and I had it towed home. This morning I put water in it (it was a gallon low even though I had filled it three days prior). I got a jump start but the car wouldn't start. It cranked and cranked but would not start. I did notice a leak of water from near the bottom of the engine. I am curious as to what the problem may be and why it is not starting now.
