Changed the dizzy and rigor. Still doing it after fitting..... So thinking about the boost solenoid as mentioned before I checked the vac lines and adjusted one dubious looking bend. Boosted it to work this morning and it hit .8 no probs..... Tried 1 bar and it reached it better than before but still with judder. Adjusting the bends a bit more, so ill know tonight if it was relocating the solenoid that caused it.....
