Hi everyone, 1st post for me.
I have just bought(3 weeks ago) a 2005 Astra 1.9(z19dth) 120bhp 16 valve model. Recently the car started losing power intermittently, but is now undrivable.
When i start the car and go to accelerate,nothing happens untill over 3000rpm,then turbo kicks in and revs to max rpm. If i allow the car to drop below 3000rpm in any gear it fails to accelerate at all. After about 5 minutes the spanner EML light will come on and fault code p2279 Intake air system leak detected. I tried cleaning the EGR today(though just seen the proper way to do it by removing the valve-will do this tommorrow).
Any other ideas on this,could EGR or faulty swirl valves cause such a loss of turbo boost below 3000rpm,or possible any other cause.I have as best as possible checked vaccum and boost pipes ok.
Any help is much appreciated.
