tintin360 Posted December 31, 2013 Report Share Posted December 31, 2013 Hi, I'm after some advice, over the last couple of weeks my lupo has been juddering. Whenever I put my foot down, either for speed or to get up a hill, it starts to judder and feels like it's about to stall, the car is also feeling sluggish. I've checked for error codes by my £10 handheld code reader from flee bay but no codes show up.Would this be a sign that the coil pack and HT leads need replacing? If so, is it difficult to change a coil pack? I've had a quick look under the bonnet at the coil pack and from what I've seen there four bolts holding the coil pack, and a black plug at the back of the coil pack.Would I have to disconnect the battery to change the coil pack?Any help or advise would be great.CheersSteve 1 Quote Link to comment Share on other sites More sharing options...
lupo1.0se Posted December 31, 2013 Report Share Posted December 31, 2013 Could be the egr valve needs cleaning.... Quote Link to comment Share on other sites More sharing options...
NOCK Posted December 31, 2013 Report Share Posted December 31, 2013 I'd clean the throttle body before I even thought about spending any money on doing anything else.If the throttle body is clean then take a look at your spark plugs, then leads, then coil pack I'd say.

Thomas96 Posted December 31, 2013 Report Share Posted December 31, 2013 When mine started doing that it was my egr valve. We tried cleaning it out but landed up having to replace it in the end Quote Link to comment Share on other sites More sharing options...
