so yeah, when i pull up to a stop now my rpms drop to 0 and the vac goes to 0 and the car starts sputtering and a ton of black smoke starts pouring out the exhaust and about 10 seconds into this the car will catch itself and rev the engine up w/o me having to give it gas. ?@!?

for anyone who doesn't know what's going on my inline fuel pump died and the shop is replacing it sometime later in the week supposedly, it was SUPPOSED to be today but those lazy f*cks haven't gotten the part in yet. for the last week i've been driving around keeping the car under 0psi because when it was discovered i had a bad pump, they disconnected it for the fear of it dying under boost (and shutting closed, killing the engine). THIS SUCKS. but yeah, it was fine for a few days on the stock pump, and i haven't gone into boost AT ALL since then. my a/f guage still isn't reading anything b/c i'm pretty sure i fried another o2 sensor, my oil guage still isn't working b/c the sender is dead. and i'm pissing people off in traffic b/c of all the smoke. it's kindof funny actually, people will be walking behind me and it'll just start pouring out...whatever, i'm pissed thou. any ideas?
