#67 of 305 Stalling and starting right away
May 05, 2008 (4:43 pm)
I have a 1995 Buick Lesabre with 184,000 miles on it. The car runs well when it is cold. It doesn't give me any trouble when I drive it 18 miles to work. The check engine light comes on when it warms up and it stalls. I can shift it into neutral and it will start up right away. I have new plug wires, spark plugs and a new air filter. The gas filter was replaced about 10,000 miles ago.
The car will stall about 5 times in a row when just driving 7 or 8 miles. It seems to always stall a slower speeds and never stalls when I driving over 55 mph on the highway. Someone suggested camshaft sensor. I would appreciate any ideas.

There are many things that can cause your problem. The "good" thing is the check engine light coming on. Take it to Advance Auto, Autozone, whoever in your area does free check for codes. It should have a stored code since the light's been on.
Be sure to call them if it's not a local place where you know, and ask them if they have the connector to check on your car. There was a year or two where the connector is odd before ALDC II became the standard.
Remember the code is only a symptom. Don't replace parts based on that. Use that to diagnose. My first real thought is the MAF sensor. Or the IAC may be sticking. Both of these are on the throttle body and can be removed. The MAF can be cleaned but the little wire is fragile. Use CRC cleaners that are for intake cleaning, such as CRC on the shelf at stores.
Crankshaft sensor usually has people saying it won't restart right away. Yours is up there in miles thought. I'd have to go look for camshaft sensor symptoms. Yours may or may not fit.
The check engine light code needs to be read first.

I got some CRC Lectra parts cleaner and sprayed it into the connectors for the MAP sensor, Throttle control sensor and the Idle control sensor. This seems to have solved my problem. My check engine light no longer comes on and my car is no longer stalling.
Thank you for your help,

Hi, If you got yours to stop with just the cleaner sprayed on the connectors, you're lucky, I took mine to a shop where the owner read the codes and then he said that he just knew what to look at next, It was the MAF sensor, he tried cleaning it ( the two wires you see after removing it that is) but didn't work, I went to a salvage yard and got a used one for $ 20.00 ......now it Runs Fine. Hope this helps

Thanks for the message. I thought my problem was fixed. I found a used IAC sensor and placed it into my car. I didn't have any problems for about a week. I will try the MAF sensor and see if this makes in work again.

Another thing you could do that fits alot of your symptoms is have your ecm checked by autozone they will do it for free and usually takes all of about 15 min to remove it and replace it with a few good tests if tests good check your crankshaft or camshaft position sensor make sure the wires are not crimped and that the connections are clean and tight even though alot of ppl report when bad that the car wont start until after it sits for a while is not always the case I was having the same problem andas u can see fro my post been changing stuff and everything and was told by a buick dealership to try it and It worked the stall and miss are both gone. but just something to try cause its free to test and it controls everything your replacing just as i was.

I have a 92 Buick lesabre and sometimes it won't start We have change the plugs and wires .we also have a new battery. It seems to only do it when it's hot. But no engine lights come on. It also has enough fluids. We think it might be the thermostat. What do you think? Also where is the thermostat?? have any pics?

I would go to the library and pick up a service manual on your car. There are at least two that are still out on that model Lesabre. I also go online and look at the parts on the Auto Zone website. Good Luck.
