Hi Buddy just had this with mine, see my threads, I didnt have any Vac leaks,

But My Bailey Dump Valve was the problem in the end, went back to my standard Re-circ valve and now is all good.

If I remember right, I had this problem when I put my DV on, and later a cone filter. I pulled the ECU out and left it for an hour, put it back in, never saw the fault again, might be worth a try?

I also tried this, fault code didnt come back but my car started to suffer, from a Hold back under partial throttle, real bad miss. and under powered.

It Got really bad , i had noticed after a run when i'd turned the car off the dv was still open, then another time it was shut.

This dv was faulty after replacing it with the standard recirc' all the power was back.

thanks for the replies will check for leaks and try new dv and let you know how it goes

NO need to try a new dv, just go back to the standard recirc, if it cures it you will that the dv is at fault.

leaks on the rubber unions on the cambelt end of the inlet manifold - part of the PCV system - common fault.

Quite fiddly to get to.
