Not sure about either delay (in the starting or in the acceleration/ engage). I read something a while back about the automatic...That some felt like you had to really "gas it" when on hills or certain kinds of terrain, to get the rpm's up and then it would kind of "launch" or rev causing the driver to have to immed apply the brakes. Not really sure about the truth to any of this or validity of the comments. I just know that a friend of mine has an auto and when wheeling this past wknd, I heard his engine rev up like he was fixing to run us all over. It was in a sort of off-camber section where I believe he needed some xtra torque to keep from sliding sideways, and I think he had a wheel or two off the ground. Not too sure about the exact conditions, but [man] I thought he was gonna launch that JK hard. It sounds like maybe a throttle return spring or something is needed. Maybe he just hit it too hard, or his foot slipped, but I don't think so.
