2000 Buick Lesabre Driver assistance Problems

the 2000 Buick Lesabre is a wonderful car basically a tank with the 3800 SERIES II you cant go wrong but the tiny little plastic part holding the throttle cable will dryrot even with a garage kept car under 150k miles please get them replaced I was driving and then the part came off and it got wrapped around the bracket and it took off I melted the breaks I wasn't stopping due to constant gas so I flipped in down into neutral to stop the vehicle from accelerating after i found a spot to pull it off the road but you can also put your foot under the peddle and pull up on it while pressing the breaks if you cant find a safe area while this is happening but i didnt relise it was happning until i hit 65 because the road i was on was a 55 and before i knew it i was going 90 luciky i live out in the rural areas

The plastic pice holding the throttle lines snapped off and my cable went under my bracket and it took off I destroyed the Transmission putting it in neutral to stop the vehicle after I had gotten it stoped the fire from the engine was small I will recommend this car and yes I do want another one but it is a common issue I will recomed this car because the body is made out of steel and they are basicly tanks with the 3800 Series II and it was easy for me to spot what was happening and get ahead of it before it got worse I drove 5 miles with this happening before the engine overheated and caught fire
