Car ran good and stopped. Starter was bad. Changed it and it started knocking while running. I noticed there is a knock sensor on the side above the starter but cant find the plug to reconnect it. Is this the cause of my motor knocking all of a sudden?
Is the knock sensor required on a 2.0 spi engine? I cant find the connector on 1997 Ford Escort

Does it knock 'sitting still' with engine running?

Looks like the knock sensor is not used in 97 but is in 98 according to the Mitchell1 wiring diagrams. I just had a 97 with a knock sensor installed on the back of the block, but no wiring harness connector to go to it. Perhaps they installed some 98 spec. engines in some 97 models & just left the knock sensor disconnected. Your knocking noise is likely a mechanical issue, not related to the knock sensor.
