Car has 115k mileage but has been standing abt 6 monts. When i acelerate slowly it runs fine. Also when i touch the throtel at idel it sounds like misfire but think its fuel delivery ? Idels rough drives verry jerkey and tends to mis at hi rpm. No engen smoke what so ever. Did notice fuel spray out the top of what looks like a fuel preshure regulator under the intake asembly near fire wall but stoped after abt 10sec thin tiney spray. Any ideas what could cause the power loss and jerky prob ?

There are O rings for the supply and return lines on the fuel rail and they should be completely dry. It could also be the fuel pressure regulator. It has to be 3bar and if not, that could be the cause of the poor performance.
