I have recently bought this ford focus and there seem to be a couple of problems.

1 - Creaks when moving slowly and turning - im assuming it is the sway bar links?

2 - It has just had a new clutch but when you lift up the clutch pedal in neutral, it sort of rattles a little bit. Sounds as though it is a rough bearing?

3 - Main problem - car feels underpowered.

Sat at 2k revs, a very slight touch on the throttle will make the car accelerate ok, but press further and the acceleration does not increase.

There is no black smoke, I have followed it in another car to check.

There is a slight sound of air blowing in the car, sounding as though it is coming from behind the steering wheel.When looking in the engine, there is a load of pipework there which I think is part of the EGR system? There is a container type cylinder with a couple of pipes and connectors going into the top of it.

When driving the air blowing sound starts as the engine picks up revs and then disappears when you press in the clutch. The sound remains constant when you leave the clutch engaged but lift off the accelerator.

It sounds as though there may be an air pressure leak somewhere, but im at a loss as to finding it? I did find that a small hose pipe that was supposed to be plugged onto the air filter box was uncoupled, so I reconnected that, but it hasnt made much of a difference. Any advice people? I cant get the turbo to spool up with the car stationary so I cant listen for the exact place. There must be a good way of finding splits/leaks etc?
