Viewed the site for the first time last week looking for ideas after suffering similar symptoms to "gutless Disco" ie ran out of steam going uphill, RPM fluctuating at 2000 by +- 200, very slow acceleration and hung up at 70mph. Feared the worst after finding the pipe between turbo and pump intact and intercooler hoses OK - turned out to be fuel tank breather pipe blocked, a quick blow through and off we go.
