when the engine is running although I can easily put it in any gear when the engine is switched off. I have also noticed that when I try to put it in gear the car starts to pull forward slightly despite clutch being fully depressed. The gears started being a bit difficult a few weeks ago but now won't engage at all - any ideas? I have adjusted it on the nut below the clutch pedal but this hasn't made any difference.
