1989 lincoln towncar
When you check or adjust timing there is 1 wire that you disconnect at the distributor. This is to adjust the initial timing. Once that wire is reconnected the computer will adjust timing based on different sensor inputs.
Basicaly a knock sensor detects detonation and signals the computer to retard timing. The are very sensitive to installation torque. They cannot function properly if the installed too loose or too tight.
A couple of articles on knock sensors.
Good luck and let us know. :)
