After a morning of decorating, an hour to play. I figured I'd check the ICV and the flame trap. ICV removed, didn't look too bad, but given a clean anyway. Same goes for the flame trap.
I only found out last night that with the LH2.4 system you can get the little code reader box thingy to cycle round and operate the various parts like injectors, ICV and so forth. So with the ICV removed but connected, a test cycle applied and it's working fine.
Also checked the plug on cylinder 1 to see if it was sooted, not too bad.
And the net result of my fiddling, apart from just beating the rain? Absolutely no difference whatsoever...
The first 15 - 20 seconds on cold start it idles nicely at about 1300rpm as I would expect, but them drops to 500 or so, stutters, picks up to 1500rpm, drops, repeat. Pickup from this is not good.
Throttle body gasket should be here later this week, so I'll strip that and do a dark room check of all the hoses too.
