Test drove a 2004 base Crossfire with the 5-spd automatic. Question is, what would cause it to do this: was heading downhill into a left turn and was accelerating, let up a bit as I went into a right turn uphill, but then I accelerating a bit to go up the hill, the car jerked like a rear tire locked up, then when I went to accelerate again it seemed like the car was in neutral (dumb me, why didn't I look at what gear the car said I was in), the engine would rev but it almost seemed like it wouldn't go anywhere (though it was, however downhill), I pulled the car off the road at what seemed like 2 miles from where it did this (it had not gone away), I put it in park and checked for warning lights, which there were none, backed up fine, pulled back into the road, stopped to check for light again, but everything was fine there after. I actually went back around to see if I could make it do that again, but no dice. Has anyone else experienced this? Could this have been "Limp" mode? It seemed odd how the car kept going but there was no since that any power was being put to the ground.
