I have a 1995 Bonneville SSE V6 3800 Series II and would like to know if it has a supercharger or not? I am also having a problem with my oil preassure, after about a half hour of driving when i come to a stop the gauge drops to nothing, bongs, and the check engine light comes on, but when I hit the accelerator, the oil preassure returns to normal, but when i stop again... bong. An oil change seems to stop this problem for a few days, but it keeps coming right back. Any ideas?

Welcome to your first post on AF.
The engine code or 8th digit in vin no will tell you what engine it is.
Post it back here.

On oil pressure you need to hook up a manual test gauge and take oil pressure readings
Check cold and hot and at adle and at 2500 RPM and post back pressure readings.
MT

8th digit of vin = k

Not supercharged, follow MT-2500's instructions, use the oil preesure switch port on the oil filter adapter for a gage hook up.
