Hi mengo_her,
The knock sensor is located below the intake manifold, just above the oil filter, bolted onto the engine block, near to the cylinder head gasket.
Yes, a bad knock sensor can cause the performnce issues. Likewise, if the ignition timing is set wrongly, the CEL would indicate intermittently.
