I've got a factory service manual for my '91 NA, and there's no torque pattern (sequence) for the main plenum bolts (among many other Nissan omissions) in it. Anybody ever found one from another year FSM maybe ? I've been working through a full re-hab of my E.F.I. system, ready to remount the plenum & sure don't want it ruined by a vacuum leak. Could really use some help on this one.
