#1468 of 1497 Re: '90 Buick LeSabre stalls when lukewarm. [ubisum] by scoske Sep 25, 2008 (9:53 am)
Replying to: ubisum (Sep 24, 2008 11:36 am) It sounds like it may be a problem I had a while back with my 88 Chevy van. There is a coil that comes off the crank shaft that sends a signal to the CPU and tells it to send spark when the crank shaft is spinning. The coil on my van went bad, but it was ok while the engine was cold. After 10-20 minutes when the engine was hot the engine would just quit. It would only restart after sitting for an hour or so. I replaced the coil and it ran perfectly again. Check to see if this is a possibility. If your 90 lesabre has a similar coil, then this could definitely be your problem.

Replying to: ubisum (Sep 24, 2008 11:36 am) It needs some diagnosis to try to eliminate some of the potential causes. Fuel pressure from the 18 year old fuel pump? Connection problem at the electronic spark control under the coils? Other connection? Crankshaft position sensor? Camshaft position sensor? (I think this one gives code)   This car really needs to be hooked up to a Tech II or better device while being started and running to see record what happens when it acts up. It sounds like it's doing it regularly and somewhat predictably.   Are there any codes when read by a code reader at Advance Auto or Autozone.

Replying to: imidazol97 (Sep 25, 2008 12:36 pm) Keith aka imidazol97 : Thank you for your most relevant response. Every bit of knowledge that allays my ignorance on this matter is most appreciated. The way I figure it, this is a problem that my mechanic, who’s been in the business for about twenty years, has never encountered before. Apparently the combination of a truly knowledgeable mechanic and a really honest one is impossible to find, at least for me. All too many of them tend to see a customer’s automotive ignorance as an opportunity for profit. Replies to this message: imidazol97 (Nov 03, 2008 8:18 am)
#1471 of 1497 Security Alarm malfunction by henderson5 Nov 03, 2008 (7:25 am)
The alarm horn and lights will go off on my 1998 randomly and frequently even if the car is not locked. I have tried various methods of locking the car with and without remote, manual and nothing seems to work. Is there any way to deactivate the system? I can't find a seperate fuze. Sometimes the security light on the dash board will be on but most of the times it is not on. Thanks for any help

Replying to: ubisum (Sep 26, 2008 10:50 am) I suspect the fuel pump more after hearing some callers on repair shows on radio stations through the last months. A Cincy mechanic/owner used to explain how he would hook up a set of pressure gauges for the fuel line and duct tape it to the windshield. Then he would drive the car and watch the pressures if the car acted up. He would use the car for errands for the shop/body shop that he owned and get in some realistic drive time in the car.

Replying to: rbritland (Mar 01, 2004 3:23 pm) Might be a stabilizer problem. I had a similar problem with a 97 Regal. Probably a standard platform that these cars are built on. Fred
#1474 of 1497 Air conditioning by xtramile May 24, 2009 (3:38 pm)
My 2000 Buick Le Sabre Limited's air condition blows cool air but not cold air; it has been recharged but the problem still persist. Does anyone know how ti fix this problem? Replies to this message: imidazol97 (May 24, 2009 4:47 pm) xtramile (May 26, 2009 10:19 am)
#1475 of 1497 Re: Air conditioning [xtramile] by imidazol97 May 24, 2009 (4:47 pm)
Replying to: xtramile (May 24, 2009 3:38 pm) Which air system? Manual or automatic air with digital readout. If the latter, is the passenger air also not cold enough?   Where are you? Is it super humid where you are? Very hot when this is occuring?   Is this true after driving at 40+ mph on open road for 5-10 minutes?   You might have an actuator not moving a vane inside the HVAC box all the way to cool and some air is going through the heater core?   BUT the most likely would be that the freon isn't correctly charged. Was it done by a professional with gauges on the high and low sides of the system? Or was it charged by someone like me with a can of R134a from Walmart with a do-it-yourself gauge on the low side only and brought up to pressure with that backyard system?   However there have been more than minimum reports of actuators not working correctly. Most common is they quit and dont' move anything at all.   Curious, does it go full hot when you turn the temp to full hot? Try putting it on 90 for a while if you have the automatic system and then bringing it down to the cool settings at 60. Replies to this message: xtramile (May 26, 2009 10:19 am)

Replying to: imidazol97 (May 24, 2009 4:47 pm) Thanks for your response!   I have the automatic air with digital readout. The passenger side is also not cold enough.   I'm in Las Vegas,NV where it is very hot and dry.   I had it recharded at PepBoys.   I set the temp to 90 and it's work fine; it gets really hot but from 75 to 60 air blows the same. What do u think?
#1477 of 1497 Sputter.. 2000 LeSabre by tkcolorado May 30, 2009 (12:06 pm)
I have a 2000 LeSabre Limited with about 68,000 miles on it. I bought the car about a year and half ago. Our mechanic checked it out from top to bottom and said it would be a great car.   Now i'm having some trouble with it and not sure what it is. Driving down the highway today at 65mph. Drives fine, until we start to slow down. I notice its missing. Then we get to a stop its VERY noticeable.   As I push the accelerator it really starts to miss/sputter. I turn the car off in the parking lot and we let it sit for a good 2 hours. Come back and it starts fine, but immediately starts to sputter/miss again. All the way back home on the highway it lacks power and starts to sputter/miss.   Now when I turn it on it really doesn't want to run smooth. I did notice the other day that the fuel gauge was wrong (when it gets below 1/2 a tank it just goes all over, registers as full, etc.)   Someone suggested it was a fuel pump. If it is, how is that replaced on this car? This person said they couldn't remember if it was a tank removal job or if this years car had an access panel through the trunk.   Thanks.
