Ok the problem is she is bucking and jerky sometimes, like when i let not completly off the gas but like just to slow down it jerks and bucks. Also she dies on me sometimes. When i get on her real hard, i'll put her in neutrl and she'll idle low then high and then back down and die. sometimes I don't even have to get on her hard and she'll die. The owner before me had the coil packs changed and a smaller pulley put on the car. Since i've had the car i've put a new air filter and changed a pcv assembly hose, I just want to see if anyone can help

Have you tried cleaning/replacing the mass air meter? I've seen several problems when they get dirty. Most consist of surging/idle issues. Also you said the pulley has been changed. Did the other guy get a retune to make sure everything was in check?
