My Buick is having this problem for 6 weeks now. Service can't seem to find what's causing it. In the morning and in the evening after starting the car and driving a few feet (out the driveway) it will start shaking and loose power and possibly stall out. After restarting it runs just fine. Service replaced plugs, wires and did general tune-up. Still did the same thing. Service checked/replaced onboard computer, checked crank sensor, mass air flow throttle all to no avail. Checked Buick for any re-call activity for this problem - no luck. Any suggestions?

Change out the (EGR valve) I had a Buick LeSabre and got the valve out of a used car at the junk yard and had it put on for 20.00 and my car worked fine. These are very expensive new. I had the same kind of problem. I changed out the plug wires also but it didn't help until I got the EGR valve.

2 common items to check for on those. Make sure the fuel pressure regulator is not leaking or seeping fuel out of the vacuum port. In severe cases you can remove the vac line and see the fuel coming out. Otherwise you can install a VAC pump on the regulator and leave VAC on it for 5-10 min and then check the vac fitting for fuel.
The second common problem is the coil towers corroding. Remove the spark plug wires one at a time from the ignition coils and look for a burnt or rusted coil tower. It will be pretty obvious. Those are the 2 most common issues with the 3.8 of that model year currently.

I am not sure this is a guess. But once my thermostat failed open and the car took forever to warm up. During the start up period the car ran terrible. The engine didnt have enough time to heat up. So maybe you can check into that.

Take the element back to advance and tell em examine the altenator. The battery in easy terms works to crank the vehicle, then the altenator keeps the battery juiced up. i'm going to wager you in no way necessary a battery- those idiots caught it to ya buddy.
