hope someone can help with this.
I have what seems to be a strange problem. When accelerating to at least 2400 RPM in 1st gear and then completely removing my foot from the gas, the engine RPM drops all the down, eventually stalling.
It doesn't seem to be happening in any other gear and only manifests itself at RPMs higher than 2400.
When idling the RPM is around 500-750 and hunts within about 100 RPM ryhtmically. That is to say, it's going up and down in a predictable and consistent pattern.
It doesn't seem to be happening when the vehicle is in Park.
It's the 4.6L V8 Petrol version.
