1999 Buick Regal - 3.8L V6 Supercharged 234,000 mi,
while driving down the road the car would just shut off, and i would have to wait for a few minutes before it starts again
1999 Buick Regal - 3.8L V6 Supercharged 142,500 mi,
Car would shut off randomly, at first only after it had been running for a while, but it got worse and would stall any time/at least twice per day. Replace mass air flow sensor 3 days ago, hasn't stalled since.
1996 Buick Regal - 3.1L V6 287,000 mi,
studders at take off and acts like it looses power at times
2000 Buick Regal - 3.8L V6 240,000 mi,
Car dies varies times no special speed or RPM Finally security light comes on, pointing to the key and/or ignition switch. Traded to wife's original, seldom used key After the three minutes, car started drove the 1800 miles home with no more problems. Buick dealership wanted to replace crank sensor at $200. Maybe a good guess generally. The key is just another thing to check. Book also suggested just clean the key. At the 240000 on the 7000 mile trip the 3.8 did not require any added oil and still gets from 29 to 31 MPG at freeway speeds. Finding it hard to replace with a new car.
1999 Buick Regal - 3.8L V6 Supercharged 170,000 mi,
Car stalling repeatedly, suddenly and without warning or sluggish performance. No DTC codes found with Actron Scan Tool. Had shop run tests, they recommended either MAF and/or CPS replacement. Replaced MAF myself, but stalling continued; then ran code scanner again, and popped P0336, stating pending CPS problem. Considered this definitive proof of cause of stalling. Scheduled CPS replacement.
the car stalls aleast twice a day weather i drive at high or low speeds.
2004 Buick Regal - 3.8L V6 Supercharged 90,000 mi,

2003 Buick Regal - 3.8L V6 100,000 mi,
Car runs fine until putting signal light on to turn right. Car will sort of stall - all lights on dash come on and then car will suddenly restart on own. Sort of a glitch in power.Does not happen every time
1999 Buick Regal - 3.8L V6 249,000 mi,
car runs at low speed <35 mph without a problem. However, when it runs at high speeds it shuts down. It will restart after several hours, but will shut down again. Coils are good, spark plugs good
