i think this is the manifold pressure circut, its the only sensor on the intake manifold that i can see. its plugged in and its not leaking that i can tell.

 

Check the tube going to the purge solenoid. They often crack durring disassembly.

 

is that the purge solenoid ? i checked the line and it looks fine. no cracks or bends. i cant really see where it goes to, but it looked just fine. is that solenoid supposed to be somewhat loose ? the retainer bolt is tight, but it wiggles easily. it was like this before i touched it. could i have gotten some debris inside from all the junk that is in my intake manifold?
