i thought the problem was the egr, but after i got a mate to see what was wrong i started the engine and rev the engine he told me that the swirl bar doesnt move, what does that mean the manifold is new, i have open the behind and found that if i pusg the small bar which is located on the actuator drive it moves fine so why doesnt it move when i rev the car, i assume thats way there is no power because the swirl bar isnt moving
