Last week my intercooler pipe broken so I had no power and black smoke. I went to my local dealer for the pipe but it needed to be ordered from Ford. I patched up the old pipe just so I could get to work. This worked fine. On the way to the dealer to collect my pipe it split again black smoke and no power I had to drive in 2nd and 3rd with my foot on the floor just to get the car home. I replaced the pipe and expected every thing to be fine but its not. The question is what can I check I have no black smoke the turbo is working the car will happly driver at motorway speeds its just taking a long time to get there. Hope someone can help.
