Default fuel pressure

hi robin, I have a spare fpr you are welcome to have if it suits, it is a 3 bar pressure regulator for a 2.5 m50 engine, part number 0280160503. I have a thread on this forum about something very similar happened to me ....I replaced maf idle control valve tps, fuel pressure regulator, injectors cleaned... the problem was in the end so simple, a faulty connector on the alternator, dropping voltage to ecu, and causing every fault code in the book, but essentially gud idle and spluttering under fueling was intermittent and frustrating.
