SOURCE: Radiator Fan's Run All The Time
There are 2 things that will cause this to happen. 1. The thermostat needs to be replaced and, 2. The coolant sensor can be bad. When I had this problem, I changed them both at the same time, she been just fine since then. Also, I had the check engine light on, and got the code from AutoZone (it's free!)

the fan motor could just be bad, you can test this by removing the fan and connecting a wire to each terminal and to a battery. the wires hooked up one way will spin the fan and the other way will spin the fan backwards so you cant hook it up wrong. I hope that helps you out!

Here is a diagram of the firing order for you 3800 engine. Cylinders 1 and 4 are misfiring because the operate under the same "Coil Pack" and the coil pack has unfortunately gone bad. O'Reilly sells them for between $30-50 depending on the amount of warranty coverage you want. To replace, simply unscrew the screws that hold the coil pack in place. WAIT before unplugging the plug wires. Place the old coil pack and new coil pack next to each other, unplug one plug wire, then plug it to that same port on the new coil pack. then do the same for the other plug wire. Then screw your new coil pack in place, and start you car. should run fine!

Here's a quick check list
for most common cost of SRS / Air bag problem.
Dirty contacts on driver and passenger seat belt buckles
Dirty contacts on seat belt connectors (under seats)
Dirty contacts on driver and passenger sides weight sensors (under seat)
Weight on passenger seat
(Example: grocery package trigger SRS / Air Bag light on the way home.)
I recommend you to pass an vacuum over the contacts and use CRC electronic parts cleaner to rule out connectivity problem.
I DO NOT recommend disconnecting the negative battery connector to clean the code(s).
Without the code(s) the dealer will takes "BILLABLE" time to reproduce the problem.
Please rate my answer if it is useful to you.

I have a 2000 Bonneville - I had a problem with the car stalling out - then it did not want to start back up. (When it did it would idle up and down and then die) I changed out the mass air flow sensor - now I have not had a problem. Good luck with it.
