Hi. I currently own an automatic 1996 Saab 9000 CDE 2.3 Turbo and Im having a bit of a boost problem. Under acceleration when the car is not fully warmed up boost alternates between 0.5 bar and 1.1 bar, but when the car is warmed up the boost does not rise over 0.5 bar. What is normal boost pressure? Is it overboosting when cold or is it not boosting to full capacity when warm? Also what could cause the boost pressure to go up and down when accelerating?
