'90 SPG Base boost - Saabnet.com Bulletin Board
Thank you for your post!
The SAAB 900T employed the BOSCH LH 2.4 LH fuel management systems between 1990 to 1993(Plus 1994 Convertible). This did use an air mass metering over-boost protection which would typically render a trigger at 16+ psi charging pressure.
The SAAB APC system should bring the 900 towards 11-12 PSI(8/10's Orange On Dash Board APC Gauge). If creating this pressure, the APC system should be functioning.
A simple DIY test would to disconnect the two pin connector from the APC three way control valve(BCV)which would bring the 900 to base boost pressures and this should be a noticeable decline in charging pressures(7 PSI).
Best of luck with this 900 project!
