I have been having issues with my mk4 1998 astra kicking and juddering when accelerating. It feels like something is blocked sometimes and then if I keep accelerating it suddenly feels like something has popped open and there is loads of power. Sometimes I can stop this kicking by easing off the accelerator and then slowly accelerating again.
I have also noticed that when it does this the car sounds like something is blocked and anyone else who has heard it in the car always seems to think it sounds like the car is not getting fuel.
I have already blanked off the egr valve but so far this hasnt helped at all. I have considered doing the paperclip test but my astra seems to have less pins on the connector then I have seen in pictures. Any ideas?
