Hi lads,

On my ST lately the turbo pressure will stay at the very top and when you press the pedal you get no turbo but after a few seconds the turbo kicks in. Now it does not happen all the time but i cannot figure out the problem.

No whining noises from the engine, the turbo boosts, even had ford take a look when it was in for a service and they said nothing showing on computer and no pipes loose or cracked.

Any ideas?
