Ok, so as you know, had it mapped and got lots of problems pulling timing after, narrowed it down to avcs (runs fine with it disconnected), since then, have replaced avcs solenoids, removed stripped and cleaned avcs pulleys, retimed car/cam belt, and today removed sump and replaced oil pick up tube just to rule it out, the car was better after changing the solenoids but still not right, it's had compression and leak down test week before mapping and mapper said figures were fine, next thing is a bore scope just to make 100 percent sure all is well in there and if so then get it remapped by someone that actually gives a flying !Removed!
