krnau 0 Posted June 4, 2010 Hi all, All of a sudden, MPG started to show really "optimistic" values, so I directly suspected of a vacuum leak. I decided to "delete" the vacuum pipe that's attached to the back of the cluster (early style cluster), so I unplugged it from the inlet manifold (it was attached to a t-fitting piece which I deleted) and connected the one that attaches to the ECU directly to the inlet manifold nipple, right. NOW, the dash is getting no vacuum at all, so it should show either 0 or 99 mpg (min, or max, or whatever) as it has no signal.... BUT NO!! It's showing the correct MPG value now :| :| :| :| :| with the vacuum pipe disconnected. How is it possible?¿!?¿!? I guess it's getting the MPG value from the ECU??? Let the experts come arround and give me some help,, please 8) Quote Share this post Link to post Share on other sites
