Basically if I accelerate hard the car will start to boost then it will suddenly just cut everything to the extent you nearly smack your face on the steering wheel. After doing it the once it will just keep doing it no matter how hard or soft you accelerate.
I had the whole front of the car off the other day and found a split in the Michelin Man hose at the front which I replaced with a Samco hose. After putting it all back together the problem is still there. I also have noticed that the bolt on top of the wastegate is unwound quite far.
The last thing which I think is very much connected to the problem is when you are accelerating, before it ****s its pants you can hear the air being sucked in(or pushed out) and when you change gear you can really hear the dump even though it just has a standard recirc valve.
Someone please help as it making me want to get rid of the car. It has done this since the day after I bought the bloody thing!
Oh yeh and its a 3B engine.
