Vectra 1.8, 2000 reg, 16 valve,

intermittent fault
juddering badly on deccelaration and feels like it is going to cut out
a light flashing on occasionally (engine management presumably)
garage seem to be struggling to diagnose

Any ideas?

I'd be grateful for any suggestions I can pass on to the owner.

Possible ECT connector fault, there is a kit of bits to fix this fault from
vauxhall.

Thanks for the suggestions, but ...

I gather it is only happening when foot is taken off the accelerator at
about 70 MPH (and only sometimes).

Surely a connector fault would show up more or less at random?
