GershVR6 23 Posted February 28, 2017 Report Share Posted February 28, 2017 Good Day I have noticed recently while driving my VR6, that it gives off a strong petrol fume while driving, specially inside the car. I have checked, and there is no miss fire or any over fueling taking place, the car is actually very fuel efficient. Is the any sensor i should replace to eliminate the strong fume it gives off? Please advise Regards Gershon Adonis Cape Town South Africa Link to post Share on other sites
VR6Pete 1,456 Posted February 28, 2017 Report Share Posted February 28, 2017 Couple of questions. - Have you removed charcoal canister at all and left clear pipe venting? - Have you checked condition of rubber lines? especially where the hard lines meet the rubber hoses, mine had perished and noticed that I had a minor leak there, over the years the rubber lines do become more porous. - Have you removed PCV valve at any point ? I once ran with just a filter on the rocker cover but fumes (very similar smelling to fuel) was overpowering. - Other sensors etc.. that can contribute towards fuel is blue temp sensor, MAF and Lambda.

GershVR6 23 Posted March 1, 2017 Author Report Share Posted March 1, 2017 Hi VR6Pete While reading on the forum and a few other sites, i am sure my issue is due to my 4 pin MAF being faulty causing the car to run rich. When i unplug the maf while idling, the engine dies and does not start without it plugged back in. I am sure that unplugging the MAF should not have this effect, am i right? Another friend suggested maybe the oxygen sensor could also be faulty? Before replacing the sensors I will have the exhaust system checked for any leaks as well.

Jason 5 Posted March 1, 2017 Report Share Posted March 1, 2017 I'm sure mine dies when the maf is unplugged... I remember having a wire breaking down and it would just cut out Link to post Share on other sites
