bad idle

Hi there folks, hopefully there are some gurus out there that help me. i have a 1999 acv 102 with the pp 0.5 injectors and retro fitted cruse control. other than that it is totally standard. i have put a new crank pully, new crank timing pully on. the timing is scattered 38-65 and duty cycle...

ok guys, I really need some input here please.... My van had been running fine until the other day, indeed I was about to commence PP upgrades! It is probably coincedence but it seems to have started after a diesel fill up at an esso garage. Anyway, next morning it was terrible to get started...
