Well nothing good to report =/ Chinese STAR arrived and works well, but doesn't really give me any more info that I already had - a misfire on cylinder 2, but only at mid-rpm. No other codes present and all live data etc looks good.
Fuel pressure regulator did nothing, only thing that helps (makes it go away) is unplugging the water temp sensor (which tricks the pcm into giving it more fuel). Put new intake seals all round for good measure
At my wits end now. Wondering if it could be a PCM fault or an invisible vacuum leak in the plastic intake manifold around cylinder 2. I'd like to get a smoke test done for that and then maybe a good 'scope guy to observe pulse width on the injectors.
