S2 running rich

[BillC99]

Hi All,
My S2 2.9 is running very rich.
Any ideas before I start ripping things apart?
I have used a star tester and it doesn't show any faults.

Fuel pressure, coolant temp sender, air flow sensor.

Any of the things Peter has suggested could give you a problem, possibly also the Throttle Position Sensor?

If you can get hold of a Granada or Sierra Haynes manual there's a little bit about mixture adjustment but that won't compensate if something is broke!...........

For fuel pressure - missing/blocked/leaking vac reference line to FPR?
