fuel pressure regulaot or vacuum leaks are the only real things that can cause this.
i had an et with a shitty regulator and its fuel economy was crazy. just swap the complete rail and reg with one from someone off the foruum. its not a bad job to do does it stall at all? as if so its a vacuum/boost leak

well i have another fuel rail here from another engine but ive also got a guage coming tonight to test the pressure.
Would i put the guage between the pump and rail or after the old regulator.??

Probably just before. Are you sure that One or more of your injectors are partially stuck open? Ie bore wash. Fuel reg is the likely condidate but could also be a knackered afm

Would it run rough with a knackered afm??
Possible boost leak around crossover pipe ends as it does stall when pulling up to a junction with brakes on

ok cool well i pulled the plug off afm and it stalled.
wound in the screw on the afm a bit no real change. I have not pulled codes yet was going to look tomorrow i think. not sure whether it will give me codes properly as the loom has been cut and shut. ill try anyway. I have pulled a plug and its very black/sooty and i have connected a pressure guage to the fuel and it shows just over 2 bar so thats ok. Would a water temp sensor cause this also and does it have a cold start injector??
