Had a good head scratch over what to do next with my heap of junk....sorry, Rover 75.
Compression test is OK, bit of variation between cylinders but not unexpected given the manual work done to the head. Leak-down test is absolutely fine. No manifold or exhaust leaks (contrary to what a local garage tried to tell me).
And yet it still runs incredibly rich with the fuel trim all the way negative (lean). Won't idle without some throttle when cold.
Fuel pressure regulator? Partially blocked IACV?
