2001 mazda protege 1.6 P0106 code vacuum probs
 

I seen babyhueys post on this and looking at baro sensor circuit performance

map sensor and sol valve issues ... right now i have no vacuum to it the line i'm using is going to the valve...behind the throttle body dont know the name of it but it has a vacuum tube on it.... 2 probs there is that the right line? its a long steel tube behind the intake manifold and its clogged

now this is what i'm trying to figure out

Vacuum line from backside of intake manifold connects to the solenoid and another small vacuum line connects between the solenoid and sensor.

I get the small line connection
this other line... back side of intake.. where exactly is it? (the other end) i'm using the 1 off the UNKNOWN valve is that the right one? if so if i take off the valve and clean it? think the vacuum will work then has anybody tried that?

Ive cleaned the throttle body maf sensor and idle air control for the P0507 code also pops up with the P0106

can somebody please help me fix this Hoopty
