Dumb question but does the MAP sensor on the 86 SVO need to be connected to the vacuum system? If so, is it connected to the vacuum line tree on the firewall on the drivers side? A couple years ago I pulled the engine from the car to do some work on the engine and thought I took enough photos to help me put everything back together. Unfortunately I lost many of the photos and am now wondering if I hooked up the MAP sensor correctly. Currently the engine is hard to start, runs rough and stalls. I have already tested and adjusted the throttle position sensor, replaced the idle air control valve since the engine originally had a fluctuating idle and the valve was sticking, even after cleaning it.
Thanks
