i have a 2002 wrx wagon, with 100k. when i start in first, it doesnt seem to have that jump that i've experienced in other wrx's. it almost has the feel as if i were starting in 2nd. other than that the turbo kicks in just fine at about 3 and it pulls pretty quick. just wondering if anyone has suggestions as to what it might be. Fuel injectors, spark plugs, clutch...?
