Question about 1999 Buick Century
All engines have vacuum created in the intake manifold, because the pistons are pulling in air into the cylinders from the intake manifold, resulting in a pressure drop in the intake. A leak is caused when the intake manifold gasket is bad, or when a vacuum hose off the intake becomes disconnected or breaks. The hose will then **** extra air into the intake, causing a higher than normal idle, maybe a rough running condition, and can be identified by a slight whistling noise at the break or at the disconnected end of the vacuum hose.

SOURCE: Buick Regal brakes
Sometimes (when changing the brake calipers on disk brakes, or changing wheel cylinders on drum brake systems) the mechanic will clamp a vise grip pliers on the rubber hose to prevent hydraulic fluid from dripping out. This can break the internal fiber lining in the rubber hose. Then the fluid flow can be blocked. When you press the brake pedal, fluid may not flow to the wheel or wheels. As you press harder, the fluid may suddenly flow through the line, causing the brakes to suddenly activate.
Or an even more likely problem, your brakes drag (stay on) and get hot, because the fluid cannot flow back to the master cylinder when you release the brake pedal. In other words, when you press the brake you force fluid through a partially blocked rubber hose. But the return of the fluid (backwards through the rubber hose) is caused not by pressure, but just by equilibrium, a balancing act. Well, if the line (rubber hose) is blocked, the fluid stays in the caliper or wheel cylinder, and the brake is still on, and the brake gets hot.

I had the same problem with my 95 Lesabre. The owners manual says to take the key out, and wait 3 minutes(until the light goes off). It should fire right up.

I found the problem. It was the crank position sensor. There was also a cracked vacuum hose connecting to the diaphragm on the fuel rail. Replaced both and my 92 Buick no longer dies. For the guy who's Buick was dying when using the turn signals - replace the crank position sensor. One of my symptoms of my Buick dying was when I used my turn signals. Use of turn signals places a varying load on the electrical system which messes up the crank posistion sensor if it is going bad.
