I have a 2005 1.6 Ford Focus Ghia with a strange problem. I live in Spain. During the winter months that are colder and a bit more humid my car has a noticeable hesitation at approx 1900 rpm. The car also feels very slightly jerky throughout the lower rev range. When the weather warms up as it is now the problem goes completely. I have changed the plugs, leads and the coil pack with no improvement. It seems to be temperature/humidity related. Can anyone give me any idea what the problem might be? Regards Colin

Have you changed the o2 sensors?
