Anyone have any ideas on what might cause that? The only things I can think of currently is that the fuel pump might be the culprit, unless something else decided to be problematic all this sudden. I was truckin' down the highway, turning slightly high revs.. not really (only 4500), in third gear accellerating when it just stopped accel, and slowed down quite a bit. This is an auto, so I took and put overdrive back on, tried pumping the gas as I'm decel'ing, and still nothing. I slow down to about 47mph, and notice I have a little control. Pulled over to the side of the road, checked to make sure I wasn't smoking, or leaking, and everything seems like it's working as it should. As long as I'm below 1900 rpms, it works. As soon as I try to get over that, it just bogs down, almost like it's not getting enough fuel. In my 280zx this happened once, and it turned out that it was just the connector at the AFM. Is this something known to happen with the 300zx? Thanks!
