Iv'e tried searching for an answer but with no luck. came out this morning to find the boost gauge not working and obviously no boost. Have got manual boost valve. It's got abbott ecu and only 56k on the clock.
Heyes, it sounds as if you have a hose loose somewhere or perhaps a very badly shot dump valve. I'd look for broken or disconnected vacuum hoses in the first instance, and other larger hoses that might have popped off. Look at the underside of the throttle body, as that's where I had a hose pop off my Aero.
Thanks for all your advice, have checked all hoses etc. as much as I know how with no luck. If haggag01 would like to call me on 07831 460087 or pm me, maybe he being the most local could check in more detail.
Finally found the problem, it was a torn hose behind the throttle housing. Couldn't see it for looking at it. Thanks for your input Haggag01, it would still be good to meet sometime if you are passing the bay, you've got the number
