Hi I will continue to wait anyway for your answer and please let me know if you get the video which I try to send you that's show exactly what I want to tell you. I don't have any mechanics a round me to trust them all of them are about money sadly but that's the truth. Thanks
Hello the video hasn't come through but this sounds like the exhaust may be leaking ? this will create a loud blowing noise and a lack of powerI'd start by checking all the exhaust joints - where the manifold joins the head and the down pipe joints just before the catylst - the best way to do this is to start the engine from cold and feel around each joint with your bare hands - feeling for exhuast gas blowing over your fingers - you'll have about 30 seconds before it all gets too hot
