Hi Guys,

Have the above car in which surges under load, no MIL, no faults present.

Suspect a fuel delivery issue, wondered if anyone has any specs please?

We have the specs from AD which are:

lift pump - 0.75bar - we have 1.1bar
delivery pump - 4.0bar - we have 3.1bar, which drops to 2.3bar under load (5th gear up a hill)
have not checked flow rate - anybody have a value?

Have scoped MAF - OK peaking at 4.6V

I'm all ears

Cheers,

Gerry
