Vacuum Lines Renewal - Saabnet.com Bulletin Board
Replaced the three small diameter vacuum hoses from the throttle body, tee and blow off valve to that small device near the firewall. Original rubber hose was cracking and brittle.
After a few drives to let the computer recalibrate, the car idles and pulls better than before. Idle is a steady 850, and there is less vibration when the A/C is on at idle. I used regular rubber hose, not silicone hose.
Recommend everyone try this DIY process. Hardest part was moving the wiring harness on the firewall to get access to the connections. Before you reattach the harness connections (those red tabbed clips like on the ignition cassette connection) spray the CRC electical contact cleaner in the contacts as that location picks up a lot of fine dust over time.
There is a decent video on youtube by Trionic7 that shows the how to.
Hope this helps.
