Grasscutter Posted February 21, 2006 Report Share Posted February 21, 2006 hey, just a quick question, my car just decided to cut out on me and when i restarted it wasnt firing on all cylinders from the sounds of things, really lumpy idle and lots of smelly black smoke comming out of the back! but when i drove off to get home it was fine, performance as usual no problems, when i got home again running at about 500rpm juddering, cutting out, and black smoke.ive checked for head gasket syptoms i dont think its that, im thinking its ethier a spark plug/ht lead etc problem?has anyone got any ideas as to what it could be?thanks James Quote Link to comment Share on other sites More sharing options...

SweZooT Posted February 21, 2006 Report Share Posted February 21, 2006 just a small Q.. have you changed the cambelt recently? Quote Link to comment Share on other sites More sharing options...
Grasscutter Posted February 21, 2006 Author Report Share Posted February 21, 2006 no ive not changed it yet, its on my list of things to do Quote Link to comment Share on other sites More sharing options...
SweZooT Posted February 21, 2006 Report Share Posted February 21, 2006 my guess is either something on the idle side of ignition och the cambelt jumpeda notch. Either way i'd take it to a tech asap.. Quote Link to comment Share on other sites More sharing options...
BridLupo Posted February 22, 2006 Report Share Posted February 22, 2006 Sounds like an ignition problem. Either plugs or a lead. Does you car have one or two coils? If it has a single coil one of them might be on the way out Quote Link to comment Share on other sites More sharing options...

Molten Jules Posted February 25, 2006 Report Share Posted February 25, 2006 Have you checked through all of your HT circuit? HT leads are well shielded and dry place but on my 1.0 the ditributor cap and rotor arm were badly pitted.Changing them has made such a difference - still not going to break any records but fuel consumption is much better, car is better to drive and runs much better from cold. Not sure about your engine but may be worth just checking from plugs backwards.Good luck. Quote Link to comment Share on other sites More sharing options...
tshirt2k Posted February 25, 2006 Report Share Posted February 25, 2006 Cant guess. You need to get it scanned with Vag com or similar Quote Link to comment Share on other sites More sharing options...
BigMon Posted February 25, 2006 Report Share Posted February 25, 2006 Sounds like an ignition problem. Either plugs or a lead. Does you car have one or two coils? If it has a single coil one of them might be on the way outI'm probably totally wrong, but does the Loop have coils? I thought (certainly on the GTi) it's just spark plugs and HT leads.

Tigz™ Posted February 25, 2006 Report Share Posted February 25, 2006 on my 1.0 the ditributor cap and rotor arm were badly pitted. What distributer cap? style="vertical-align:middle" emoid=":blink:" border="0" alt="blink.gif" /> The Lupo doesn't have one! Quote Link to comment Share on other sites More sharing options...
