Buick - Lesabre :: Stalling - Engine Just Shuts Off At Random Times
I own an 87 Buick Lesabre Limited Coupe [URL] ..... I have driven it for the past 6 years with no major problems, but just now it has begun to have a stalling problem. The engine just shuts off at random times. Doesn't matter if you're at a red light or driving in traffic. She will stall, then after 5 minutes will start up again, and stall again. So, I took to it to my mechanic & he changed the ignition module & mass air sensor. I picked it up, and the 'Service Engine Soon' light went on, and then she stalled a few minutes later.
So, I drove her back to the shop (stalling several times on the way), and my mechanic changed the crank position sensor, and she still died. He read the trouble code 42, so he changed the ignition module again. I picked her up yesterday, and she made it home without stalling, but the 'Service Engine Soon' light still goes on after 5 minutes of idling, which leads me to believe that the problem lies somewhere else. Could it be an electrical problem (wiring, fuses, computer) that is causing the 'service engine soon' light to go on & the car to shut off? What else could it be?
Buick - Lesabre :: 2000 - While Driving Sputtering / Stalling / Hesitating From A Stop?
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.
Buick - Lesabre :: 1995 - Stalling Randomly And Intermittently / CEL Flashing With Fast Clicking
My 1995 LeSabre (3800 v6, 62K miles) has a stalling problem, no engine power, but still has electric. It happens randomly and intermittently. Most times it will restart but has been increasingly difficult to restart. The only indicator prior to stalling is the speedometer "surges" and then the loss of power. Dash lights come on (oil, voltage, CEL). Sometimes the CEL will flash in time with a fast clicking that I believe comes from the fuel pump relay under the right side of the dash. Until this clicking stops the engine will not restart. I have replaced ignition control module, and then the crank and cam sensors. Replaced PCM with rebuilt and it was worse (defective?) and put the old one back in. Mechanic can't find any codes to determine what is causing it to stall, except possibly PCM is bad.

1997 buick lesabre, 4 door, v6. It was having problem stalling out. This weekend a friend and I lifted the car and replaced the fuel filter and fuel pump. Drove great Saturday and Sunday. Today I get in the car, starts up without a hitch. I start heading down my street and realize I am having to push my brake pedal in ALL THE WAY to get it to stop and even then it's slow to stop. So I back up, pull the hood and check the brake fluid. Sure enough, it's low, so I run to Advance, grab some fluid and fill it up the max line and think i'm ok. Start the car up, pump the brakes a few time and notice nothing new. I get out and realize I have a very steady leak in front of the right rear wheel of fluid. It's a steady drip in two places. Is there something I could have done to have caused this. The only line we messed with on Saturday was the emergency brake line and it's clearly working (I tested it).

I have a 94 buick lesabre custom that is stalling intermittently and runs rough intermittently. We have had it for diagnostics and it could not read the codes. We changed the computer and it still can't read the codes. The diagnostic tool says it cannot connect when it is plugged in or it displays white flecks like snow flakes on the tool screen. It is an OBDII. The pin structure of the data connector port is two pins top row and bottom row two pins some blanks and one pin. We don't know how to fix it with no diagnostic codes and we don't know what to do to get the codes because we have changed the computer.

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.

View 1 RepliesLeSabre :: 2001 - Buick Losing Coolant
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 '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.'.

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...

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?
View 12 RepliesBuick - Lesabre :: 2002 - Won't Start After Overheating
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.

View 3 RepliesBuick - Lesabre :: 1996 - HVAC Fan Will Not Shut Off
My son's car overheated yesterday due to a sudden crack in the radiator. He had it towed to me. There was no evidence of a blown head gasket or cracked block, so I replaced the radiator. Since the battery was dead, I put the charger on it. When I did that, the heater/AC fan began to blow. The only way I could get it to stop was to disconnect the battery. Even the ignition switch had no bearing on the fan.
I do not know if the overheating and this problem are related. It may be just a coincidence, but it is odd.
This car has a slide to regulate the blower speed. It is not one of those "Select a temp" automatic ones. It will blow cold air out the AC vents when AC is selected, but when the OFF button is selected ambient air goes to the DEFROST vents.
I suspect a relay is stuck, but what relay, and where is it located?
Buick - Lesabre :: 1995 - Shaking At Low Speeds
I have a 1995 Buick LeSabre with just over 100,000 miles on it. Recently it has begun to shake at low speeds. The car shakes as if it were driving over a rough gravel road, and makes a sort of chugging noise when I step on the accelerator at speeds from 15-25 miles per hour. When I accelerate beyond 25, the shaking stops, and the car stops making the chugging noise as well. It drives beautifully on the interstate, but horribly when I am in town. After taking the car for a drive on the interstate for about 30 minutes one day, the shaking at low speeds actually ceased for over a week, but then came back. The "check engine" light has not come on. I maintain the car regularly, getting oil and filters changed, fluids filled, etc. I'm wondering if this sounds like it could be caused by a problem I can fix myself, or if I need to have the car looked at by a professional.
