Sometimes I can't wait for my car to warm up, because I'm late for work already. I like to drive it slow to warm it up, but when I shift from 1st to 2nd at about 3K, the car hesitates when I let out the clutch. Is this because my computer is still in closed loop mood, and it can't deal very well with the change in load? When the car warms up I have no problems. Oh ya, its a K20A3, not the type S.
