jono213 Posted December 10, 2018 Report Share Posted December 10, 2018 Hi Guys, My car is running rough at idle but have already had a new set of ignition leads, coil and sparks in march so am suspecting a vacuum leak. Does anyone have a vacuum diagram so i know where im looking for damage? Thanks Quote Link to comment Share on other sites More sharing options...
mk2 Posted December 10, 2018 Report Share Posted December 10, 2018 Do you have a diagnostic thing? Cheapest is probably a bluetooth to phone thing.... could be anything. welcome to club lupo! Quote Link to comment Share on other sites More sharing options...
jono213 Posted December 10, 2018 Author Report Share Posted December 10, 2018 No codes were showing but P0401 popped up this morning. Egr was already replaced on Saturday though... Quote Link to comment Share on other sites More sharing options...
Rich Posted December 10, 2018 Report Share Posted December 10, 2018 Did you clean the ports so that it flows? Little bit more to it than just changing the part. Blockage can occur before egr. Quote Link to comment Share on other sites More sharing options...
