Might be maf, disconnect and go for a spin about 10 miles, if it cures the problem you need a new maf if still the same not maf related

GTV V6, ex 166er

that is a classic maf symptom.
Vauxhall astar 1.7d uses same maf and is considerably cheaper. Just swap into original tube.

could be a split Air Intake Pipe. I had a split on mine and a little flat spot around 4000rpm.
