2002 D4D Avensis Limp mode?

[cgmd4d]

Have a 2002 2.0 D4D Avensis, when warm it has a flat spot that comes in around 3500 - 4000 revs... clears after a few seconds normally. The loss of power came back in around 70mph and wouldn't accelerate anymore! engine management came on then..... Any ideas thanks!

Probably the scv apparently these give trouble on the d4d engine? When was the fuel filter changed? & have you got a diagnosis on it?

[cgmd4d]

@frankie406 Yeah had filters changed recent enough... hoping it wasn't scv valves... must get it on the computer see what codes are showing up
