croc86 Posted July 5, 2009 Share Posted July 5, 2009 Hello everyone. Does anyone know the official reason why a 1.8 durotorque engine would repeatedly increase in revs slightly i.e 2000 to 2100 when changing gear whilst accelerating!?! Only I have seen reasons on Vauxhall and Nissan forums saying it's because the temperature of the Cat nedds to be maintained high to allow for lower emissions. Seen other reasons suggesting it's to ease deceleration. It's !Removed! annoying that's all I can say and has been noticable 1 week after purchase. Can anyone confirm these reasons to be true or is the car gonna have to go back already for ECU or DMF modifications??? Sorry but don't know much about Focus Diesels..... Thanks Quote Link to comment Share on other sites More sharing options...
