I am getting a rather loud engine knock. It sounds like it is coming from the top end of the motor. Has there been a problem with the Focus that may cause this? Where should I begin to look? I changed the spark plugs and wires. No. 4 plug was a little wet. No. 1, 2, 3 looked okay.
have the same problem?
