I'm having stalling problems with my Buick Somerset Regal. I've had this car for several years now, and it has stalled many times while I was driving. For an instance, I was driving at about 70 mph, and suddenly, my car just shut off. Next thing I knew, the Check Engine light was on. I brought it to my dealer, but nothing helped. I already bought a new battery, hoping it will fix the issue. Still, it continues to stall on me. What should I do?

This is a common problem among this particular model of Buick. Owners complained of frequent engine stalling, to the point that they consider this car a lemon. The manufacturer, however, never issued a recall to have the problem fixed. Since it is now up to you, you might want to check if the mass air flow or crankshaft position sensor has failed. These parts are responsible for detecting the mass flow rate of air entering a fuel-injected internal combustion engine. They are important because they ensure the delivery of correct fuel mass to the engine. When any of these two parts fail, the engine stalls. It is important to have them fixed or replaced as necessary to keep your car from sudden stops.

I've had my Buick Somerset Regal for almost two years now. It just hit 122,000 miles last week. I've never encountered any problem with it. I drove it to work last night, and it was fine. But when I went home and started it, it cranked up but turned off right away. When I stepped on the gas pedal, it stayed running. But if I really pushed down on the gas, the engine began to do a coughing sound. It seemed like it was not receiving appropriate fuel. There was no Check Engine light though, which was weird. What's happening to my car?

There are several reasons that may cause your vehicle to turn on then die in an instant. You may try replacing your idle air control (IAC) valve. It is responsible for controlling the amount of air that bypasses the throttle plate. When this part fails, it can cause poor idling or even stalling. If this doesn't work, then you might need to check if the torque converter is locked up, especially if it dies both forward and reverse. You can also check the mass air flow sensor if it is still working perfectly.

I just bought a new Regal in an auction, and I was really impressed with its performance. However, after driving it around, I turned it off. Since then, it won't start. I had to wait 15 minutes before it fires up again. I changed the mass air flow (MAF) sensor, but nothing happened. What should I do?

This problem usually happens to cars that have failed crankshaft position sensor. This part sets ignition timing, supplies the RPM signal, and determines engine speed. When this part fails, you will experience trouble starting your car. You need to replace this with a new one to bring your car back to its good condition.
