Gasoline Engine Problems of Buick Lesabre - part 1

Throttle valve plate sticking. The gas pedal has to be stepped on hard when you first start up after setting a while. I'm told this is a common problem with the unit uses on many of their vehicles mine is on a 2001 Buick Lesabre with a 3800 engine. Waldecker pontiac, brighton, mi told me this item wasn't covered on the extended warranty I purchased (6yr/100000 mile) I had 94,000 miles on the vehicle but the problem has been around for at least 10000 miles. I now have 101600 I'd like to know why it wasn't a warranted item. This also could be construed a safety item as when you step hard on the pedal the car surges forward slightly. I'm aware of it so I automatically hit the pedal and release.

98 Buick Lesabre. 3. 8 driving up hill, down hill, coasting, it doesn't matter. 1 or 2 times a week the engine just dies. Sometimes I can catch it full throttle and it will pick up and run fine. Or throw it in on the fly and restart instantly. New fuel pump and filter usually starts good. Some times I have to stop cranking it after 5 sec 1,2,3 times before it starts. This only happens 1 time every week or two. I can't let anyone else drive the car for fear they will pull out in front of a truck and the car will quit.

This 1997 Buick le sabre , in very good condition , exploded with a fireball and sending plastic "shrapnel" and engine cover parts out to a radius of 24 feet. Thank god none of the three people trying to start the car with the hood up were standing over the engine bay.

I had at least 6 different times that I would go to start the engine and it would only hum, not start. I took it to the dealer while under warranty and they said they could not duplicate the problem. I asked if they checked the battery cables and they said yes. I asked this as I thought that was the problem, a loose battery connection. I knew they did not check, as the battery is under the rear seat and I placed a kleenex box in a marked position and it was exactly the same when they returned the car. It finally just wouldn't start at all, so I had it towed to a repair station (not the dealer) to be fixed. They said the battery cable was loose and arking and they were surprised that I didn't have a fire under the back seat. The reason for my complaint, I don't want anyone injured or killed from a fire under the rear seat in any 2000 Buick Lesabre. Hope you will make gm check all battery connections on any model with the battery under the back seat. Thank you.
