Hi! I'm having some rev-related issues with my 1.7 '98 Puma. After excluding most of the causes (TPS, ICV, Vacuum-leaks, Some dirty plugs, Cluch switch), I'm down to the PAS Pressure Sensor (sensor or plug) underneath the left front side of the car. Is there any test I can do to rule out the sensor and can someone give me the part number so I can replace it with the right if needed? Thanks a lot
