elvisgraham Posted May 2, 2007 Report Share Posted May 2, 2007 Hello,I am the owner of a VW Lupo 1.4 S. My car was overdue it's service by a few thousand miles and performance wasn't great. Car has just come out of the garage having been serviced and had a blowing exhaust. Car back into the garage to get the exhaust replaced. I now have a putting noise coming through the exhaust when the revs drop back down and I still think the performance of the car is still poor. I still get the feeling the car is holding back.Is it possible that the car just needs to go in for tuning or something? Could it be running too rich?Any suggestions would be helpful.Thanks in advanceAlan Graham Quote Link to comment Share on other sites More sharing options...
LoopyLing Posted May 2, 2007 Report Share Posted May 2, 2007 On of ours did this putt putt putt noise big time (as well as stalling frequently and lots of soot). I've blasted the throttle body out with my new favourite chemical, Carb Cleaner (mmmmmm) and it's spot on now. Quote Link to comment Share on other sites More sharing options...

heartagram Posted May 2, 2007 Report Share Posted May 2, 2007 Generally when using carb cleaner you just undo the airbox and spray it directly into the throttle body while someone revs the engine. If you do it on your own its most likely to stall. Not sure about Lupos cause they are fly by wire so dunno if you can manually up the revs in the engine bay like older cars? Either way its easier with 2 people. Quote Link to comment Share on other sites More sharing options...
luppit Posted May 3, 2007 Report Share Posted May 3, 2007 yeah theres a throttle cable just next the the throttle body so it wudnt really be that hard if your good at balancing haha Quote Link to comment Share on other sites More sharing options...
