Sterling badges now fitted:
A couple of other jobs have been attended to. First was the intermittent wipe which, no matter where I set it, would only work on 3 seconds interval. The intermittent wiper control box is under the dash, on the relay panel which sits where the CCU is located on a mk2.
I nabbed the delay box from my mk1 scrapper, installed it and found no difference. The only other thing I could think of was the wiper stalk - so I took that off the scrapper and that did the trick. I can only assume that the stalk switch was faulty - but I now have a range of about 1-10 seconds sweep so I'm happier (especially with the weather we've had these last few months).
The other job was the continuing saga of my fast idle speed. Having previously suspected the Electronic Idle Control Valve (EICV,) I discovered (thanks to perusing the workshop manual) that there is a separate Fast Idle Valve (FIV) on the car. This one is thermostatically operated, and sits in an awkward position, tucked under the throttle body and the EICV and is not easy to get at.
The FIV is heated by a water supply which runs from the inlet manifold, to the FIV and then on to the EICV in series. God alone knows why Honda felt that this was a clever setup, especially when the whole system is above the water level of the rest of the engine, and therefore prone to airlocks.
I removed the FIV (not easy) and dismantled and cleaned it out and then found that there is some adjustment to be had, so screwed it right down to minimise airflow through it. Once refitted and bled the results seem positive - but I'll need a proper cold start tomorrow just to be sure.
Of course, after struggling to remove the damned thing, I discovered that you can remove the top of it (two screws) and screw down the collar inside to adjust it!
