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.

40psi. double checked lines no leaks. maybe something unplugged? but not sure why it would run fine at idle and cruising its right when I go into boost car sputters like its leaning out, added more fuel on oad map but thats not it still does it. again no errors. idles at perfect 1150-1180 rpm @ 16hg like its always been.

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.

havent been paying much attention to the FD. but both secondaries failed, weird because the are both new only a couple weeks old.
