right ispv cleaned, but still no luck!!

im mate (a ford technitian) reckons we should look at the ecc control valve (think thats what he said?) next, and check the vacum is pulling about 19 on the mercury scale. as this could be sending false readings there for the car over fueling then conpensating buy underfueling then more fuel again etc.

My (lambada) hego sensor wires are a bit worn, so i may try replace this also.
