Hi ya guys,

A friend of mine has recently rebuilt a series 2 rs to standard spec. He's got the lump back in and connected everything up however is having some problems with the electric fuel pressure regulator that sits on the side of the metering head. When the electrical device is disconnected the car seems to run / idle fine, however when he connects the electric fuel pressure regulator it runs lumpy as hell and dies on idle.

Suggestions ?

Thx, Swanny
