w reg vectra petrol on one spark plug car runs well aftyer being parked but after running for awhile it starts to feel juddery and its hard to pull away is it because of petrol on plug if so whats the cure is it the coil pack
Yes, once the coilpacks on these fail they tend to show symptoms when it gets hot.
You could get it checked, but probably cheaper, easier and faster to just renew it unless a friend has the same engine and you can borrow one.
