I've got a mazda protege 96 and i have been doing a lot repair and check on that vehicule

His problem is bad accelerating, idle is unstable and the timing at regular idle is about minus 10. Timing at basic timing is ok

the only thing that i find that is not working is the egr boost sensor selenoid so no reading of the map known as the egr boost sensor . But the selenoid itself work the wire to the ecu and the connection are ok. I even put a red light in my car to see if the selenoid is working.

the egr was change and the coolant sensor.

the thing i want to know is how to air it and what other sensor or condition put on this selenoid

The MAP should have its own vacuum line and be totally seperate from any othte rsensor so it gets a solid vacuum reading. I dont understand what it is you want to know? Each solenoid has a specific purpose and they dont do the job of another solenoid
