Hi to all I'm hoping someone will have some answers to the problem I'm suffering with.I've owned an x reg(2000) 1.6ls 8v Astra since July 2008. Since I got it I've had trouble with loss of power,juddering/kangerooing and subsequently on occasion cutting out.
Having read through many posts on this site I removed and cleaned the egr valve with carb cleaner. On a journey of about 50miles in March the e.m light came on, on investigation this was diagnosed as cam sensor and replaced.
Thought this had sorted the problem but the other day during the same journey the car began juddering again. My problem seems to occur once I've done about 10-15miles and am doing between 40-50mph (noticed the rev range was 2000-2500), if I drop below 40mph or 2000rpm the juddering settles down.
I've replaced the spark plugs(as I mainly do short journeys commuting to and from work) and the cambelt has been checked (was replaced when I bought the car) and tension/position is fine.
Any thoughts/advice gratefully received. Thanks for reading
