I have a pinging issue with my Toronado. Installed new plugs, wires, and replaced all underhood vacuum lines. Found the underdash MAP sensor and noticed that there is no vacuum line to it and figure that this is probably my issue. Would appreciate any help in how to hook this back up (Not sure if vacuum line is there or not). The underhood vacuum schematic does not show the MAP sensor. Does anyone have a schematic showing how to connect the MAP sensor?

 

I would have to look in my book ,But you might be looking at the Baro sensor,Being (in car related) the Book is diffrent Especliay for cars with Climate control .Try useing higher octain gas first before spending a bunch of $ on trial & error parts Larry
