V12 ecu vacuum pipe in boot

[sbn_98@yahoo.com]

My 1989V12 is running rich and we have found a vacuum pipe coming out of the ecu has corroded away but we can't find where it has come away from - any clues?

Should connect to the right hand (A) bank inlet manifold and connects to the MAP sensor in the ECU...not a surprise you're seeing over fuelling. Suggest that you run a length of hose around the car to test, before you get into repairs.
