Bibbles Posted August 11, 2014 Report Share Posted August 11, 2014 Hello, I recently brought a 2001 Lupo 1.0e the owner said it had a misfire problem he plugged it into diagnostics and gave it a run and both live and post data shown only misfire no pinpoint he said it could be a break in the injector loom wiring so brought a new loom (he is my old mechanic tutor from college so trusted his judgement) but before I go ripping wires out does anyone know what would cause it to periodically misfire and lose power whilst on motorways mainly but if you turn the key off and on it instantly clears. Any help would be super appreciatedAlso anyone got a top left door card plug, mines vanished and can't find a replacement ThanksBilly Quote Link to comment Share on other sites More sharing options...
Bibbles Posted August 11, 2014 Author Report Share Posted August 11, 2014 Forgot to mention it has been serviced recently by the previous owner too. Thanks Quote Link to comment Share on other sites More sharing options...
HDH Posted August 11, 2014 Report Share Posted August 11, 2014 Did the engine management light start flashing? That's the car telling you it's misfiring. And when you plug in a code reader it will tell you which cylinder exactly, allowing you to pinpoint more accurately. Could be plugs, leads, coil pack or something else completely different?

Bibbles Posted August 11, 2014 Author Report Share Posted August 11, 2014 Yeah it does flash then stays on and then some times I'll turn the car off and boom nothing? Should I check all the points you mention for corrosion before replacing the injector loom? Thanks Quote Link to comment Share on other sites More sharing options...
Bibbles Posted August 13, 2014 Author Report Share Posted August 13, 2014 Also where is the best place to get said coil pack? Thanks Quote Link to comment Share on other sites More sharing options...
DannyParanoid Posted August 13, 2014 Report Share Posted August 13, 2014 Mines got a weird misfire as well at the moment, ive replaced coilpack and plugs, next thing is the leads, as for coiloack i got mine from the local autozone, but euro car parts sell them as well!

Bibbles Posted August 13, 2014 Author Report Share Posted August 13, 2014 Is it under load or at high speeds like mine? Think before I rip my loom out I'm going to replace my coil pack and leads I think the plugs were done recently as it had a service so...

Bibbles Posted August 13, 2014 Author Report Share Posted August 13, 2014 If I were you i'd get the exact fault codes first before throwing money around.That sounds fair and more clever than my idea. The cars last owner tried but got no code but if it costs me nothing might as well try I guess... Quote Link to comment Share on other sites More sharing options...
DannyParanoid Posted August 13, 2014 Report Share Posted August 13, 2014 To be fair mines a lot of the time, but being a 1.0 i dont really tend to notice it haha! The only time i notice it is on idle and i dont really go on motorways a lot so i cant really help on that one! Quote Link to comment Share on other sites More sharing options...
Bibbles Posted August 14, 2014 Author Report Share Posted August 14, 2014 Haha ahh yes I know what you mean in the town its usually not too noticeable but on motorways it can be scary especially up hill hahaha Quote Link to comment Share on other sites More sharing options...
pedro2682 Posted September 12, 2014 Report Share Posted September 12, 2014 I have the same issue's, I've replaced Leads, plugs, coil pack. Cleaned EGR valve and compression tested with no avale. I have also had it on a cheap dignostics plug in and it couldn't find it, but if worked fine with my brothers Seat and Polo. Time to bring a hammer out to see if that will fix it x-( Quote Link to comment Share on other sites More sharing options...
