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.
Basically 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.
Good luck and let us know. :)
