Interesting. As those parts are the most likely things to be causing the problems.

So you're happy with the engine wiring, no faults in the loom? All sensor connections are fully pushed all the way in? When parts were replaced, were they installed correctly & the right way? The ISCV, how was that cleaned, rebuilt and adjusted? From memory they were computer controlled and not really manually adjustable?

Any chance of some decent photos of the engine bay and possibility of a video of the idle + trying to rev?
