Order of inspection
P0327 Knock Sensor 1 Circuit Low (Bank 1 or Single Sensor) Medium
The P0327 code means the signal from the knock sensor is lower than any real condition allows. Without that information the computer cannot detect knock and retards the timing as a precaution, so you lose power. The sensor tightening torque is the most overlooked cause.
