Possibly a plugged up cat. Bang on it with your fist and if it rattles like a can of marbles, replace it.

Check your gap between crank sensor and wheel. Could be losing the signal at that rpm if it's not close enough. Also is this Just free reving or driving. Or both

@turbo its doing it both driving & not .avance adapters said you can gap with a credit card so thats how I did it but thats one of my first thoughts just won`t have time to pull tranny til the weekend plus I was hoping that isn`t it.does the wheel /marks need to be shined up to read it was a junk yard find? thanks
