Vectra's back and they have changed the coilpack so the jerking has gone, however I have noticed that when the car is cold everything is fine, runs perfect.

Once it gets warm ( about 90 on needle ) its like it tries to stall and takes more revs in first gear to get the bite now ive been driving 15 years so it's not new to me and really cant see it being a 'charactrisic' of the car but its annoying lol

Any one heard this before ? oh 1.8 vvt
