When stopped at light or any other stop, car goes into neutral at times. If you put it in neutral and then back to drive, it will move forward normally. Sometimes it does this 4 or 5 times during a short trip and then acts normal. Once recently, on a hill I stopped and when pushing the gas, the car started to roll backwards and would not go forward but eventually, ... Read More

I have a 1991 Buick LeSabre and I have to put water in the radiator several times a day, but the engine never runs hot. When you start the car you can see the water leaking out of the side of the engine where the plugs are. I haven't been able to get anyone to tell me exactly what the problem is. Is there anyone here that can help me?
thanks a lot for your time and help.
A note about oil light. Could be sender. Could be worn oil pump and that may have lowered pressure and worn bearings. and someone noted in another discussion " These engines were notorious for their weakened oil pressure relief valves. If you have been using conventional oils and not changed oil at proper intervals, you probably have gunked up the seals inside the relief valve or in the oil pressure sensor. ... Read More
If the plug wires are still Packard which is original Gm wires, it's past due. If they're a different brand I'd go by how old they look. I'd put in a bottle of Chevron Techron fuel system cleaner (available at Walmart, Meijer, Pepboys, Advance auto, compare prices). Put it in when tank is low and then add 10 gallons or 20 gallons. Drive and see if it makes a difference. I ... Read More

At 79000 and regular service I'd want to find out what it was. The sensor for oil pressure could be bad. The oil changes he did might have been 7500 miles instead of 3500. The knock could be something other than lower engine problems. Could be a crankshaft balancer. Is it erratic or constant with ignition firing? If you know which dealer did the service, I'd go back and ask them ... Read More
it has 79000 miles and the older gentleman said he serviced it regularly at the dealership. do you know anything about a product called no knock or something like that. if you do will it harm the engine. also everybody is saying they are getting 25-30 mpg. on ther'e 91 buick just like mine 3.8 i put spark plugs in it. what can i do to tune it up to get ...

If the oil hasn't been changed for a while, check to see if it seems diluted (thin) and smells of gasoline. I'd change the oil and put in 20-50 IF you're not in a cold, cold climate. I'm assuming you're using 10-30 now. You don't tell how many miles and what kind of maintenance like regular oil changes at 3000-4500 miles it's had. I'm assuming it's wear on bearings especially if ... Read More
my 1991 buick lesabre has a knock i only hear while idling or at slow speeds 10-15 mph. the oil light also blinks on and off at times. could this be oil pump? or could it be major(bearings)?
My 1991 Buick LeSabre (with 52,000 miles) will not start in cold, wet conditions...like a wet snow/slush storm. This only happens at the first start of the day. If I've already started the car and bad weather heads in, the car will be fine. But if I have not started the car yet that day and the weather is bad...it won't start again until the air dries out. The car is ... Read More
I agree with fwilson3. I have 10,000 miles on my 2000 LeSabre Limited and am still waiting for the first thing to go wrong. The passenger headrest was replaced by the dealer because it would not maintain its adjustment. That's it. I recently read in the newspaper that the Japanese cars finished first, second, and third in terms of owners complaints. Finishing first among all the American cars, and not far ... Read More
