i"m new here and not sure where to post this.............with this site i found whats wrong with my 1999 4x4 xlt 3.0 with 160k on her........( i love this truck)..................................
my 4x4 and the a/c and heat wouldn't work right so i tracked the vacuum lines and found this thing under the air box with 2 vac lines and 3 wires ........
when i unplug it it runs like POOP and when i connect the 2 vac lines together my 4x4 and a/c work........but my check eng light is on.............
what is this part called? and is it bad to have it the way i do?........its just a light right?????
thanks to all
