Order of inspection
P0329 Knock Sensor 1 Circuit Input Intermittent (Bank 1 or Single Sensor) Medium
The P0329 code means the signal from knock sensor 1 (bank 1) cuts out or jumps intermittently. The engine keeps running, but with the ignition timing retarded and less power. You can drive, but get it repaired, because uncontrolled knock can damage the engine.
