Im assuming this is the Series I 3800? If so, if you can email me I can send you some directions on the process. Its for a Series II 3800 but it should be similar. If you cant email me, post up and I'll see what I can do.

If the engine is 3.8L SFI OHV the Knock sensor is located under hood, passenger side, front engine area, below exhaust manifold, mounted in engine block

SOURCE: KNOCK SENSOR
When a knock is detected, it sends this information to the computor, in which retards the ignition timing. If the sensor is bad, it will do this more often than not.
