Mk1GLS 0 Posted October 20, 2004 Hi all, okey doke, have a G60 that seems to have started underfueling all of a sudden. I have a kind of 'lag ' appeared on acceleration. This seems to be linked to it running lean - I have a fuel air mixture guage plumbed into the sensor on the exhaust along with a boost guage & the kick appears at the same time as the fuel richens up, b4 if I put me foot down the fuel air meter went straight into the green area in the middle, now it shows nothing for a second or 2 before jumping to green & the acceleration kicking in. Did this when I first got it & I unplugged & cleaned all the sensors on the engine this time it hasnt helped. So which one would cause these symptoms? I think shes playing because shes up for sale & doesnt want to go...... ;-) cheers Quote Share this post Link to post Share on other sites

Mk1GLS 0 Posted October 22, 2004 Hi all, found the problem! There is a small vaccuum hose goes from the inlet manifold to what I assume is a fuel pressure regulator of some sort. Although the hose looked intact it was in fact leaking air slightly. This seems to have solved the problem. So now its up for sale again!
