Question no boost???

car idles fine. idles @ 16hg, when I go into boost car car wont go into boost wide band says its leaning out but the car was fine and havent changed anything. no vacuum leaks that I can see, car even cruises (13s-14s AFR) fine until I try to go into boost no errors.

any ideas, like I said car was fine a few days ago.

ohm test them, send them out to be flow tested, check the connectors for breaks in the wire, ohm test the driver wires back to the ECU, inspect the pigtails for pushed in pins and for corrosion on either the connector pins or the injector pins.
