ghemmings Posted January 16, 2008 Report Share Posted January 16, 2008 Over the last couple of days, my engine has cut out occasionally at traffic lights/junctions. Today, it has done this at almost every stop. If I decelerate slowly, it seems to have a better chance of keeping its revs up and recovering than if I stop quickly. When it does happen the revs drop to about 3-400 rpm where it struggles, but sometimes recovers. I don't think it is the LPG system as it hasn't done it before, but I can't test it on petrol as my fuel pump is faulty. Any ideas? Link to comment Share on other sites More sharing options...
LostKiwi Posted January 17, 2008 Report Share Posted January 17, 2008 Try looking at http://www.audipages.com/Tech_Articles/enginemechanical/breatherhose.html and replacing the breather hoses. Cheapest is to use 5/8" hose from Halfrauds rather than buy the genuine item. Link to comment Share on other sites More sharing options...
Ska Posted January 17, 2008 Report Share Posted January 17, 2008 Clean/ replace throttle body or ISV Link to comment Share on other sites More sharing options...
ghemmings Posted January 18, 2008 Author Report Share Posted January 18, 2008 What is an ISV? is this an idle control valve? Which part is the idle control valve? there looks like two servos on the throttle bdy. Link to comment Share on other sites More sharing options...
alera Posted January 18, 2008 Report Share Posted January 18, 2008 Can be the plugs sometimes as well...more so with lpg where you need a really good spark... Link to comment Share on other sites More sharing options...
Malairt Posted January 21, 2008 Report Share Posted January 21, 2008 I had the same problem. Replacing the breather hoses did the trick Link to comment Share on other sites More sharing options...
ghemmings Posted January 21, 2008 Author Report Share Posted January 21, 2008 Thanks, I'll try replacing the breather hosees next. The front hose is very soft, but doesn't seem to be split. The rear hoses seam pretty firm, but it's hard to inspect them. Why do they make the car stall? Link to comment Share on other sites More sharing options...
LostKiwi Posted January 21, 2008 Report Share Posted January 21, 2008 The car stalls as the crankcase is under a small amount of manifold vacuum, therefore any leak results in over lean mixtures and it will stall. Link to comment Share on other sites More sharing options...
