JumboVR6baby 10 Posted February 4, 2012 last week i was driving on motorway then had a sudden loss of power... misfiring... and doin around 4mpg!! i crawled it home and went straight to the plugs... which were fine. had new leads last year and all were connected properly. just changed coilpack... still no good. changed no167 fuel relay... still no good. checked and cleaned maf sensor.. still no good. now it starts.. just.. will tickover for seconds then just die. still gurgling under revs. Is it worth changing fuel filter and ecu relay? Somebody help me please as im driving my girlfriends megane 1.4... sorry babe but its no 'rado.. any help will be greatly appreciated Quote Share this post Link to post Share on other sites
24V Renshaw 0 Posted February 4, 2012 Have you scanned it on vagcom? Fingers crossed its nothing mechanical. Are there any other symptoms at all? Jay Quote Share this post Link to post Share on other sites
JumboVR6baby 10 Posted February 4, 2012 nah not yet.. but i will.. smoking a lot, although it did a bit when cold. after cutting out, it struggles to start.. cranking but not firing.. cheers jay Quote Share this post Link to post Share on other sites
_Meth 0 Posted February 4, 2012 Ok what is it? 16v, g60 vr6? What did the plugs look like - dry and white or soaking wet? Have you checked all the obvious things first like burst vacuum hoses? Intake system? Quote Share this post Link to post Share on other sites
swiftkid 1 Posted February 4, 2012 By your username I'm presuming its a VR6. Any colour in the smoke? Whats the oil like? Has it been using any water? I would definitely get it on VAGCOM before you go spending money on guesswork. I had a problem with mine when I first got it, the ECU had gone up the spout and one of the injectors was constantly firing so was using stupid amounts of fuel and ran terrible. Its rare that it happens but just something to bare in mind. Quote Share this post Link to post Share on other sites

JumboVR6baby 10 Posted February 11, 2012 woohoo!!!!! Turned out to be a snagged wire to the maf sensor... Purring like a kitten... Thanks eveyone.. :-D Quote Share this post Link to post Share on other sites
Jim 2 Posted February 11, 2012 Good stuff.. I was going to suggest lambda as running badly, terrible economy and smoke is faulty lambda symptom - but also interesting to know it's a MAF symptom too :) Glad you got it sorted. Quote Share this post Link to post Share on other sites
