P0321 Spark Reference Circuit. The spark reference signal is used by the PCM to improve ignition timing accuracy during crank and at engine speeds of up to 1,200 RPM. The spark reference circuit allows the use of ignition control mode below 400 RPM, eliminating the need to utilize module mode during start-up, and also allows the PCM to calculate true crankshaft position in 1/6 the time that use of the fuel control reference signal would permit.
During normal operation, the PCM uses the spark reference signal to control ignition timing until the engine speed exceeds 1200 RPM, at which time the fuel control reference signal is used. There is no connection to the TCS.
If everything checks ok then the PCM is defective PCM.

SOURCE: 1995 pontiac bonneville stalls
I just went through lots of troubleshooting and expense on my 1996. Whenever I would lift my foot off the accelerator and was below about 30 mph, the rpm's would starts jumping around and sometimes it would stall. If I gave it a little gas (accelerator), I could sometimes keep it running. It also backfired once in a while. Starts right back up. Also, if I let it idle while in part, it would die after 1-2 minutes.
I ended up finding a hole in the fuel regulator. About a ~$70 part if you get an AC Delco, but very simple to change.

This car uses a key with a transponder chip in it. The ignition reads the value of the chip thru 2 small contacts just inside the entrance of the keyhole. These contacts are known to get dirty, wear out, or become totally disconnected from the wire they are hooked to. Use electrical cleaner in the lock cylider and run the key in and out a few times to clean the lock. This is your temporary fix. The next item you may want to try ,is having another chip key made. If this doesn't work, then you will need to replace the ignition cylinder. You can try "Plastichead Keys" for these parts. They can be reached at firstname.lastname@example.org.

It sounds like a bad connection somewhere, check the battery cable connections for corrosion and tightness, both ends. It could be the starter, starter solenoid, starter relay, neutral safety switch or ignition. Try moving the shift lever to the "N" position and see if that helps. When you say you have a dead key, do you mean you have no dash lights, (oil pressure light, battery light, things of that nature) no clicking, no nothing?
