As for vacuum. I was driving today doing some part throttle tuning. Things were going good until it started running hella rich and stalling. limped it home and could hear a vacuum leak. I found a large vacuum port at the end of the intake manifold conected to a 6 wire sensor. wasn't leaking before and can't find a hose for it?


car is a 86.5 1jz 750cc, 2jz rail, afc, hks twin, wideband, and bunch of other odds and ends. I have built my own chevys and hondas so I am competant( I think?) when it comes to working on cars.
