Reduced engine power and poor engine response coupled with increased fuel consumption certainly points towards a sensor issue. Have you scanned the car for diagnostic trouble codes? A faulty manifold pressure sensor will typically throw a code related to manifold pressure or vacuum. Do you have access to a scan tool to check the live data from the manifold sensor itself? Observing the sensor's readings at idle and under load could provide more insights into its functionality. The sensor itself can be tested with a multimeter but a scan tool gives more insight.

Thank you for the reply. I did get a code related to manifold pressure. You mentioned testing the live data. Could you elaborate on what values I should be looking for at idle and under load? I'm trying to avoid unnecessary replacements.

Given the code and your symptoms, a faulty manifold pressure sensor is highly probable. While precise values vary, at idle, you're generally looking for a manifold pressure reading that reflects the engine's vacuum. Under load (acceleration), this value should increase as the throttle opens and vacuum decreases. Significant deviations from expected values, or a lack of change, strongly suggests a faulty sensor or a vacuum leak affecting the sensor. However, given the complexity and potential for misdiagnosis, consulting a qualified mechanic for a thorough inspection might be prudent to avoid unnecessary component replacements.

I appreciate your input. It seems you were spot on. The workshop confirmed a large vacuum leak caused by a faulty manifold pressure sensor. Repair cost was 235€. Engine performance is back to normal.
