I just bought a 90 SC and just had some quick questions seeing how ive owned 3 lx's and this is my first SC. At idle my vacuum is at 20in but when im cruising it drops to 25-30. Also when in gear my idle drops to 500-600 and seems to shift into gear alot sooner..3rd gear engages at 26-31mph with slight throttle. Antilock light stays on but im sure i know its just a realy or accumilator/condensor. Fan is rigged up to a switch b/c it wont turn on by it self..also think it may be relay. Not sure about the vacuum/boost set ups yet but hopefully will be able to diagnose them like my Lx's. Any input would be great and look forward to getting this SC running smoothly. Thanks again and god speed!
