Less boost,, early stutter, new PCV system 850

Here we go. Spent Tues afternoon, and some of this morning replacing the PCV system on my 96 850 turbo auto wagon. I did make some mistakes along the way and had to retrace my steps at times. I knew an OBDII scanner was in my future and purchased one this morning to clear the codes I set (forgot to hook up the MAF, and found I had not pushed the connector onto injector #1)

Trying to drive it with the Check Engine light on was mundane. Better with the codes cleared, but it still seems a bit sluggish. When I start it up, the idle will stutter a bit then clear. While driving, it doesn't seem to have the same amount of power that it did. Then again, temps were much warmer today (85+F) and I have 89 octane (mid-grade) in it.

Is the fuel rail self-purging? Other ideas on what I might check? When I replaced the odometer gears, I pulled the boost needle off and reapplied it (no input) at the center position.

TIA,

Nick

    Verify that all of the intercooler lines are tight and not leaking. I had my connection to the throttle body too loose. Also check the lines that go from the oil separator box to the turbo, at the turbo. Check all of the other vacuum lines that connect to the intake manifold.

      Thanks Klaus,

      I found a loose hose to the IAC motor. A short drive after reconnection seems to fix both the stutter in the idle and the 'seat of the pants' boost/acceleration issue. Thank you for your suggestion, and I'm sure I will be be in need of your expertise again,

      Nick
