Excuse the new user....

I brought an a3 a few weeks ago and I'm having some issues with it, I've searched this forum high and low for answers but there doesn't seem to be any definitive ways to resolve the issues im having.

As soon as the car is started and kept stationary there's a judder, when sat in the seat the whole car has a constant light shake and idles at just under 1,000rpm. When I look in the engine bay the whole engine looks like it's shaking way more than it should. But when the vehicle is moving the judder completely goes, but once stopped at traffic lights etc it judders again.

Once the engine is warm and off its a nightmare to get it started again, takes a good few seconds to get it going again.

I've noticed when on the motorway also that in 5/6th the revs need to be above 3,000rpm otherwise it judders then too, loses power and I have to changed down to build the revs/ power back.

I've had it plugged into vagcom, a fault code has come up that there's an electrical fault on injector 1.

That's basically all the issues im having, excuse the long new post but I figured getting it all in as detailed as possible would be a good start.

Any help would be appreciated guys, I've seen many of you help people out, I'm sure someone here can point me in the right direction.
