Hi all I am at the end of my tether and really need some help. A few weeks ago I got into my 2008 tigra to find that it wouldn't turn over - it was clear that it wasn't the battery. After three attempts and dipping the clutch when turning the key I got it started.it then go worse, it started juddering up a hill like the engine wasn't getting enough fuel. Then got worse again to the point that any slowing down for roundabouts, slow cars etc it judders and loses all power likes it's going to stall. I am currently on the second garage and they are struggling to find the cause. The exhaust is brand new, I asked them to change the fuel filter and clean the lines which has had no affect.they have run diagnostics and check epc etc and aren't getting anywhere. Any help at this point would be appreciated Thank you
