Buick - Lesabre :: 1991 - Sluggish And At Times Will Stall / Vibrating At Idle
Feb 10, 2011
I have a 1991 Buick LeSabre, sometime last year the check engine light came on, and I took it into a mechanic who told me that a magnetic sensor on the timing gear broke off and that it is the problem with the car, but it would cost me 500 dollars to replace the part, because it is located in the engine. I noticed that the engine felt like it lost power, and the car started vibrating when I was idle. The beginning this year, I replaced the spark plug wires, and replaced the spark plugs, when I replaced the spark plug wires, I realized that two of the wires were broken, as soon as I was done.
I tested the car, and the power is back, but I still have the stalling problem. I will try to describe how the car stalls, I come to a stop, and when I push on the gas to accelerate, the car just conks out, so I have to restart the car, and rev it a little to keep it from conking out again, and it starts running normally. I have been told by another mechanic that I need to replace a Electronic Ignition Control module, which I can not find, and that it is possible the fuel is not getting into the chambers. I just want some answers to my problem, so the car will last me till I can get a new vehicle or something better.

I have a 1997 LeSabre with 180000 miles. I can drive the car for 4-5 miles before it stalls and then dies. the car will start to idle fast, then bottom out a couple of times before it dies. It also makes a horrible noise under the hood and sounds like the rods are all clanging together. Once it dies, it will not restart until it has sat there for 30-40 minutes. After sitting for some time, it will crank right up and then repeat the process again. My oil pressure is off the chart high and it stays there all the time. Does this have something to do with the problem of is that another problem all together? What is causing my car to die like this and how do i fix it?

My wife's 98 LeSabre will occasionally cut out or stall. It usually happens at low speeds and she thinks it may be more frequently on a right hand turn. The engine can always be restarted immediately. There is no other symptom, no check engine light on when running. The car runs well and has ~125000 miles. Sounds like an intermittent connection or short but where?

Is this a warm stall issue and if so what is the actual solution to it ?
- Car is warm it will stall out at times after start . Giving it some gas will save it from stalling
- When dead cold it will have a very sluggish start
New plugs and coils. New fuel pump fuel filter & regulator . New crank sensor . Throttle body cleaned as well as maf. evap leaks all sealed up too. battery is good too
Very frustrating. Only solution would be to leave it at a shop for at least two hours so they could do live scans. But I'd rather not pay two hours of labor for nothing.

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?

1991 Buick Regal, 3800 V6
As the title says, when I start the engine cold I get a slight puttering and drop in RPMs followed by the engine revving itself to about 1100 for a few seconds and then normalizing at 600. It has only actually stalled out a few times. This does not happen once the engine is near operating temperature.
Now, I did not notice this issue prior to doing some maintenance on the vehicle (radiator replacement and transmission service) and I've read that this can be caused by a faulty coolant sensor. Possible?
Battery is new.
Also, when I say cold start I mean summer temps here in Michigan. So it's happening anywhere from 50 to 90 degrees F.

After I start my Lesabre when cold, after about 15 minutes or so it starts idling high, usually about 1500 , but sometimes it's as high as 2300 while stopped at a light. And a few times it has been 3-4000 rpm after putting it into PARK. After it starts idling high it starts shifting late. If you shut the engine off and immediately restart it, it usually starts idling fine again temporarily. Engine has normal power and runs smooth and idles smooth. It has also randomly died a couple times while driving at 30-40mph but then immediately restarted as if there was no problem.
It has a P0121 code which is "throttle position sensor switch A circuit range/performance problem". It also has a P0420, "Catalyst System Efficiency Below Threshold (Bank 1) ", which I'm not sure is related to the issue because the check engine light had been on a long time before the idling/shifting issue started happening. Like in the neighborhood of a year and a half before the current issue, but it ran fine the entire time and got 30+mpg on the highway.
First thing I did to troubleshoot was to test the TPS and it seemed ok. Voltmeter readings were .4v with throttle closed and seemed to advance smoothly up to 4.4v at WOT. But, I tested it before the engine was hot and I don't have a Oscope. I then used some carb cleaner and shot it around the injectors and a few vacuum inlets to check for vacuum leaks, to no effect. Engine runs quiet and I don't really hear any vac leaks.
Next, I cleaned the idle air control valve which was pretty dang dirty, but that didn't seem to resolve the issue, although it may have had a slight effect because the issue seems to come and go some while driving now, but I'm not totally sure. I also tested the connector at the IAC and had voltage on all 4 pins between .4v - 11.4v approximately.
Lastly, I got the engine to reproduce the problem and then pulled and then reconnected these sensors one at a time while the engine was idling high:
MAF Sensor
TPS
IAC
Intake Air Temp Sensor
This didn't have the slightest effect on the engine... I'm thinking it might actually be the TPS or IAC but I don't want to just start replacing stuff without knowing damn near certain it's going to resolve the issue. Could a vehicle speed sensor cause this? How I should proceed from here? :?

I have a 1995 Buick Lesabre. The car jerks while I am driving or when idle as if it wants to shut off. Sometimes it jerks and then the check engine light comes on. When I described the problem to my mechanic he said that it might have been the fuel filter but then he said it might be an electrical problem. I would like to start with the fuel filter to see if that would work but I am not a mechanic nor am I an expert on cars nor do I want to spend tons of money on such an old car.

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.

1994 Buick LeSabre Custom 3.8 Litre V6 with 103277 miles.
It runs smooth when idling in Park, rough when I put it in gear when I am stopped (either drive or reverse) has hesitation when accelerating, it smooths out again when driving then it starts to drive rough at about 55 MPH.
Mechanic told me it was the plug wires. I replaced those and the plugs. This fixed the hesitation when accelerating issue, but the other issues remain (now even seem a little worse) I thought the plugs and/or wires were bad, so I rechecked the gauge on the plugs and traced to make sure I had the wires hooked up right. Everything seems in order.
I have added fuel injector cleaner, and changed the oil, oil filter, spark plugs, spark plug wires, air filter, flushed the radiator, and changed the thermostat. (For a tune up since it has admittedly been a while)....

I have a 96 buick skylark. I just recently had the parking pawl fixed because it was broken. Now when I slow down the engine idle seems to start looping and almost stall, it in fact has once. As I slow down, and I can feel the car somewhat trying to pull forward as if its not down shifting correctly. when I finally get stopped the idle will come back up and idle normally. the car upshifts great. I know that one of my rear wheel speed sensors has a broken wire.

This noise has me stumped. The frequency of noise seemed like the sway bar bushing. I fixed these and still making noise. Almost sounds like a something vibrating against the heat shield, but nothing. Seems to be front right. in the last year replaced the upper bearing struts. Shocks 4 years old. I have pushed the brakes and sound does not go away. In fact some days i drive the car and there is no noise. I just lowered the car. 132k

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.

1991 Acura Legend 6 cylinders
For about a week, my car was hard to start, and very sluggish upon acceleration. By Friday, the car was not getting over 20 mph, chugging, and semi-backfiring. I took off the valve covers and found quite a bit of oil in the 2nd cylinder, along with a crude covered ignition coil. I replaced all 6 spark plugs (properly gapped) and bought a new coil for the #2 cylinder. I also replaced the valve cover gaskets, and all 6 rings to prevent more oil seepage. After putting everything back together, making sure wires were correctly aligned, the car will not start. It cranks, but does not turn over. I put the old coil back on, and it did the same thing- crank but no start. Have I lost compression? How can I restore compression? The engine sounds so close to turning over, but not quite there. I'm stumped.

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.
