I agree about the XJ 4.0, mine was the same way. I think the amount of monitoring going in the engine bay would cause you to start throwing codes if you lost oil or coolant to the point of harm. Might be wrong, I'm a gauge fan too but that's how I compensate it. 98jgc the pistons that are not firing are hitting an air cushion that acts to launch them back down somewhat, I guess that is how they get away from too much drag. As far as the Hemi, I once got bogged down in snow in a remote area where the road was drifting over badly. No one around and before cell phones. I was looking at a really dangerous situation. My 86 Dodge pickup had a 318 in it and I credit that for saving me from a really bad experience. Since then I believe there really is no substitute for power when you need it.
