HI. I have a 2000 Buick Park Avenue,3800,not super charged. It has been stalling for the last 5 months. Has no pattern. Wet, dry, up or down hill, highway or in town. Some days it runs really great and the next day it will stall half a dozen times. Have replaced PVC valve, both oxygen sensors,egr valve,coil packs and module,fuel filter and main computer for car. Also have put in 2 cans of injection cleaner When it stalls, sometimes it starts right back up and sometimes it takes 10 to 15 minutes before it starts. Any suggestion?

Optional Information: 2000 Buick Park Avenue 3800

The first two things I would suspect are either a fuelpressure regulator or a crank sensor.Pull the hose off the pressure regulator and hold your finger by the pipe inlet.Tap the regulator with a screwdriver and see if gas gets on your finger.Smell it if you can't see it.If there is gas leaking there put a fuel pressure regulator on it.If that's not the case check for spark and injector pulse during the no start if you are missing both put in a crank sensor.
