hey guys was hoping to get some idea of whats happening to my 300zx tt, it appears that when ever im just rolling in neutral for example on the down hill the rev count starts to shoot really high id say about 3-4 rpm then suddenly it will drop so low that to the car will stall. any advice on whats going on?

Clean your IACV/AAC out. Check for major boost leaks. When I've had that happen in my garage, its because I forgot to reconnect a hose to the plenum. Also probably wouldn't hurt to check your MAF and your TPS too, plus pull ECU codes.
