<10mpg! Running horribly rich.

[StvC]

Hi all, thought I'd start a new thread away from a intro post to encourage some more input although Paul has been helpful. Car is running very rough, at 1100 rpm. Then it drops to a very lumpy juddery 700rpm and you can just smell the fuel dumping in the system. Paul offered the below advice....but was puzzled by the result.

Injectors, thin seals are a doddle, the fat ones can be a bit of a pain, but do-able.
Best news is that all of that work will come in at about £30 tops for proper OE stuff.

So using easy start, I had hoped to see this result, but when I sprayed the manifold with easy start it actually cut out.

Engine is a B200E, car is an 1988 244 Auto GL.
