Hello, I had a problem with our 94 Lesabre, Stalling while driving, and "service engine light" would come on. Scanner at auto shop said possible neutral safety switch, and definitely was a idle control sensor. Well, it still happened, well I took our car to a Buick dealer and found fuel pump going, replaced fuel pump, sending unit, and relay. And it still did the same thing, finally when engine light came on for them at shop, they said it was showing distributor module and crankshaft sensor, they replaced them, and now it runs, but a tad rough, I changed plugs and wires, but didn't help, but at least she runs.

I too have a 1994 Buick LeSabre. Stalled while in gear and as I was approaching intersections. Had the crankshaft sensor replaced twice and a fuel line, even the dealer told me it was the kind of gas I was using?? FINALLY, the mechanics thought it might be the computer. I had the computer replaced and it works like a charm!! I have had absolutely no problems since. Maybe you can ask your mechanic about the computer. New ones are about $200.00, but I was able to put in one from a used LeSabre. Good luck!

I had the same problems described above where my 1994 LeSabre Limited would die - at first it was at slower speeds going uphill, but then it happened on a freeway going about 60MPH. My mechanic had the car for a week, did all sorts of tests and finally replaced the computer that apparently was malfunctioning (think it is a chip) - have not had a problem since and car runs very well. He said that problem was a first for him.

I bought my 1994 LeSabre in August of 2005. I love it - it rides great. The price was right for this luxury car. I too am laughing all the way to the bank! It did stall twice in city traffic so I will get the computer checked out. Thanks for your advice everyone!

We have had a 94 LeSabre Limited since 1998. Bought it second hand from a Caddy Dealer. It had 64K miles on it. I asked to see the title so I could read the handwriting. Old Man's handwriting. I bought the car. We still own it and now it has 200K on it.
The compressor for the A/C went out a couple of years ago. I just didn't want to spend $700.00 on it. I was going too, but, the security system went out...$900.00 for that. That was my only real big complaint with this car was that. I did replace the front struts. That was nice. It drove like new again. I have been faithful on the oil changes (every 3K). It still gets me to work everyday. About 140 miles/day. However, it is starting to get long in the tooth. My mpg is going down. I ordered a new Corolla LE to replace this car and let my kid have it.

I have a 94 Buick Lesabre with lots of problems. please call me at 704 - 984 - 6381 if you can help. Here is the list:
1.Service engine soon light came on when car was leaking water, I replaced water pump and timing belt that fixed the water leak.
2.Service engine soon light is still coming on
3.Car stalls and takes off very, very slow. I wouldn't reccomend pulling out in front of anyone.
4.Car will cut off while you are driving and you lose power
5.Service engine light keeps coming on and Brake light comes on and beeps and does not go off. I replaced the brakes and both of these lights are still on. the car is still stalling and cutting off.
PLEASE HELP ME!!! I bought this car used and I really love this car and want to keep it running in tip top condition.

I just bought a 1994 Buick Le Sabre Custom and L-O-V-E it. The gas gauge moves a lot, but I generally know how much gas I have used and I read that is normal for Buicks.

I also have a 1994 Buick Lasabre and it stalls when I go under 35 mph, when I'm making a turn or just sitting at a light. I have had the crankshaft sensor replaced a new computer because every time I have it put on a machine another problem comes up, I fix that problem but the car still continues to stall. I have also had a new trans put in because one of the test came back for that I've had oil changes and fuel filters and nothing has worked. Can someone please enlighten me, I can't afford a new car but I can't afford to keep putting money into this and still having the same problem.

I need help getting the brake sensor to shut off. Have checked fluids and they seem fine.

I have a 1994 Buick LeSabre Limited, which I have owned for three years. Just recently the Check Engine Light came on, and the car died out. I was able to restart it, but it runs rough. I have now brought it to the mechanic twice, who tested it both times, and told me there are no codes, just one old code, and there's nothing wrong with it. Obviously somethings wrong if the engine light stays on steadily and the car keeps losing power.
This car has always been reliable. Battery is brand new. There is one gauge reading less than half (?thermostat/thermometer, top left corner) What is this and how expensive is this to fix??? Thanks, J (email@example.com)

I have a '94 Buick LeSabre Custom. The "Service Engine Soon" light use to come one every now and then. The last two days, it has stayed on. I noticed that when I take off from a complete stop, it takes longer to change gears. It sometimes gets a little shaky. Please help. I don't have the money for a new car, or even close to the amount to spend a lot of money to fix it.

Could you please send me a email of what was wrong? I have the same problem with my car. My email is firstname.lastname@example.org

I'm having stalling issues too. I took the car to the shop for a diagnostic and they said it was the computer and the crank or cam sensors. I didn't have enough for all 3, so I replaced the computer first. It ran fine for a couple of months, and the stalling came back. So now I'm replacing the cam sensor. I'll let you know how that goes.
