found the MAP Sensor and went to remove it per the Haynes book instructions which state:

1) Remove elecritcal connector from sensor
2) Remove vacuum connector from sensor
3) Remove bolts that hold sensor to the firewall.
4) Replace sensor using above steps.

After locating my MAP sensor on the firewall and disconnecting the electrical connector, I found that I had NO VACUMM LINE connected to the MAP sensor. I spent alot of time looking for a loose or dangling vaccum line, but couldnt find one.
This might just be my whole problem. So either:

A) The vacuum line is hanging down somewhere OR
B) It fell off completely.....

So my question is, where does the vacuum line connect TO from the MAP sensor???? I have attached a vacuum diagram from an 88 GT. Is this the same for my 93 LX 5.0 Convertible? Also, from the diagram, can someon tell me where the line goes into?
Please, someone help me.

Your '93 should be mass air, so there wouldn't be a vacuum line running to that sensor, as it's now a BAP (barometric air pressure) sensor, as opposed to a MAP sensor.

if you have a 93 you do not have a MAP sensor you have a BAP sensor which does not have a vacuum line running to it .....MAP sensors are only on 86 , 87 ,and 88 non california models
