I've got a z28net engine throwing up p0190. Does anyone know what voltage the fuel pressure regulator should read at idle?

did you ever get this problem sorted ?
have 2 codes which are roughly the same problem as yours
P0090 fuel pressure regulator control circuit
P0170 fuel trim malfunction
car starts crap when cold sometimes stalls
runs perfect after that
but judders when i put my foot down
do you have the same problem ?
i had this problem on my 1.9cdti 16v, it also kept cutting out every now and then, as well turnt out to be the fuel pressure regulator plug, which id advise a scrappy as vauxhall will only supply a lume at over £300 :0
