89 n/a runs the same with the pressure sensor pluged in or not

I'm pretty sure this means it went bad and that is where my loss of power is from. I was wondering if you think it is dead and which pressure sensor i need(#350 is in ther now).
Thanks for all your guys help
Brian

How about reading it out from the ECU while driving? You know, watch the meter needle swing back & forth during different throttle conditions. Then you'll really know if it's bad or not...

I thought mine was bad once too, long time ago, because it seemed to run the same with the vac source disconnected. So I got a "new" one...Only part I've ever changed on the whole car that turned out not to be the problem. Ah, the joys of knowing how to troublehoot. Live and learn...

Only when the boost sensor tells the ECU "low vacum" will the ECU work the Aux ports & VDI.
The neutral switch from the tranny will also kill Aux ports & VDI if it's open.
