Let's hope it's NOT the WUR. You said that your control pressures checked out ok, so the WUR is the last place I would look. Look at the AAR (or AAV, interchangable nomenclature). Do this: Start your car, see the low idle, pinch the hose going to the AAR. If the idle does not drop, then the AAR is not letting enough air into the intake. The reverse would be true if you had too high of an idle....pinching the hose would restrict the air and lower the idle.

Do you have both the cold and warm control pressures documented?
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
