actually the idle is fine . . . well except sometimes it lingers at 1500 RPMs then if you tap the gas it'll settle down to a normal idle. . . .
the problem is really that you have to either be on it (gas) hard or completely off of it. . . . . if you try and feather or hold the gas at a certain speed it starts bucking like you cant drive a stick.
i just talked to the kid that had the car before me and he said that it has always done that since the swap was installed
. . .hope that helps
