davej Posted January 31, 2014 Report Share Posted January 31, 2014 Hi has anyone got any ideas on this. When driving the engines seem to very very slightly fad for a second then pick up, the best way to describe it is feels like you have taken your foot off the accelerater for a split second then the power comes back. I have replaced the air and fuel filter and injectors this has improved things a lot but the problem is still there. Quote Link to comment Share on other sites More sharing options...
Skezza Posted January 31, 2014 Report Share Posted January 31, 2014 (edited) I thought a fad was something like stickerbombing You mean it judders on pull away. Clean the throttle body and the intake manifold. The throttle body makes a big difference but so can the intake manifold and they get pretty sooty on high mileage engines.

See how gunked up your egr is too. Also if your higher mileage then a tin of diesel purge would be a good start too. Quote Link to comment Share on other sites More sharing options...
davej Posted February 1, 2014 Author Report Share Posted February 1, 2014 Ordered some carb cleaner for the throttle body. I'm unable to drive at a steady speed without it pulling slightly ! It's as if you have taken your foot off the accelerater slightly fot a second put you foot down a bit and it's fine till it happens again!

It's part of the EGR I think although don't hold me to that.The other thing you can do Dave is a Diesel purge. It can make a massive difference. It did in my case, made it feel like it had just left the showroom lol.http://forums.clublupo.co.uk/index.php?/topic/97552-how-to-diesel-purge-your-lupo-the-right-way/ Edited February 1, 2014 by Skezza Quote Link to comment Share on other sites More sharing options...
