Hi having lived with this vehicle for the last 5.5 years it is now pulling harder than it's ever done before ! In fact it's a real pleasure to drive now.
When it's pulling right you can accelerate away from rest confidently, it will rev quickly and freely up to 3500 rpm and pull hard in all the gears.
The exhaust note is also different and its like driving a new vehicle.
Pull up and park for a few minutes, come back to it and the powers gone again? within approx. 1 to 2 miles of driving and the power comes back ?
There are no management lights on and there are no fault codes.
It's been de catted and does not have EGR. It's as if it can't sense load when the power has gone, is down on boost pressure or is under fueling.
Any suggestions would be greatly appreciated. It's done 140,000 miles
It had a new head gasket 60,000 miles ago, post the heat exchanger leaking coolant in to the inlet manifold. This was removed when the head gasket was replaced and converted back to the none heat exchanger type set up.
