I have an '03 legacy that has a persistent stumble on acceleration.
info: only occurs after engine is warm. Happens when flooring the accelerator from 1000-1800 rpm then goes away. manifold vac goes to zero and stays there. no codes showing. I used the factory manual as a guide and probed the computer and got good readings for all the solenoids, injectors, valves, fuel pump, etc. anything else? fuel pressure good (after filter). cleaned throttle body.
if this was a carbed car, i'd say it was in need of an accell pump tune except that the problem lasts longer than just a second like a mistuned accel pump.
