A question for all you knowledgeable chaps out there, for a while I have had a slight misfire on my '95 V6 and lack of power on climbs, I checked all the obvious things like coil pack, leads and plugs with no luck, I took it to my local dealer [by the way I live in Spain], he spent 45 minutes on the diagnostic computer and came up with a fault on the cam position sensor, he quoted a price of 45 euros for supplying the sensor, but before I replace it has anyone had experience of this failing and do you think this would cause the symptoms above. By the way for the time spent on the computer he charged me the princely sum of 10 euros!, including replacing a small piece of tube connecting one of the air sensors. The car has done 178k and I did wonder if I had a head gasket problem but the misfire is very erratic and it is not showing any of the usual signs eg emulsified oil, exhaust fumes in water etc Thanks in anticipation Graham
