Shaken, not stirred.
The first earthquake happened while we were on the freeway, and didn’t notice anything (and I don’t think anyone else did, either, since we’re about 180 miles from the epicenter). The second one, though, was much stronger, hitting while we were at home. I was watching TV and gradually got an odd sensation, where if your heart rate is just right, it can resonate with your height, and gradually start you rocking back and forth slightly. I thought it was that at first, but it kept increasing in intensity, and eventually saw the lights starting to move. It lasted for quite a while, maybe 20-25 seconds, then faded out as slowly as it started. That’s the thing about earthquakes; when you feel one start, you never know if it’s going to be The One, or if it’ll stay docile and bow out gracefully.
My brother just got his replacement engine running; you may remember that his belt tensioner locked up, shredding the alternator belt, which then ate the dry sump pump belt, resulting in zero oil pressure, and the engine was done. The new engine has a more aggressive cam in it, and he’s rather pleased with himself about the lopping idle. Having the engine running now gives time to ensure it’s solid before we head to the hill climb.
Speaking of having a solid car, I drove Midlana about 70 miles, in part to test whether adding the second throttle return spring fixed the hanging idle… nope. The engine will be warmed up so that it’s repeatable (only happens hot), then confirm whether it really is a sticky throttle plate, or the intake control valve. If it’s the latter, I’ll spray some carburetor cleaner into the idle control valve port as a quick fix to see if it really is that. If it is, it’s surprising that it’s happening so soon after a full cleaning. Of course, it could also be the idle control software loop, though that seems unlikely since it worked fine before and the tune hasn’t changed. If that doesn’t smoothly resolve itself, it’ll be time to figure it out via the ECU log files.
Lastly, some mischief has been afoot on the shop side of things, because something irresistible was found and will be here next week.
