I was told by my mechanic that i needed a stall to balance out my cam. Before the stall the car idle had to be turned all the way up (around 1100) and would still die when dropped into gear. The new stall is a b&m holeshot 23-2600 stall. However i bought it used and when i put the car into drive it moves automatically like a normal car. The car shouldnt accelerate until around atleast 2000 rpm correct? the car also doesnt die when put into gear anymore and idles around 700 rpm. Any ideas?
