Well the 4Runner is still just dandy. I found out what my off-throttle transmission whine was. I replaced the shifter bushing (from Marlin) and no more deceleration noise.
I've had a little bit of intermittent high idle. I tracked that down to a sticky dashpot. I'll keep lubing it until it completely stops. It is mostly gone.
I did develop a hard cold start only when temps are below 60˚F. I do need to track that down, but I guess I have until late October to fix that. I think it is either fuel pressure or my ICV. I don't have a start-up high idle, but that predates the cold-start problem. Seat-of-the-pants HP feel makes me think it is better if I leave the key in the ON position for 30 seconds or so before starting. It runs fine now and I'll sort that out later.
It does need body work and paint. My original plan was to do the exterior and then the interior from a logistics point of view. Sadly, my slush fund/mad money for fun stuff keeps getting depleted by the real world, new roof, new HVAC, and a few other things. Plus, I've been thinking that this might be something I want to tackle myself. I'm somewhat handy, what the hell.
Sooooo, to keep some semblance of forward progress I moved to the interior. My 4Runner is a DLX model with the 3/4 door cards. They are in good shape, but the asshat PO put some sort of weird outdoor carpet additions that were tek screwed on. Plus the DS door is a replacement from a full door card SR5 that had a speaker cut out. Door cards on eBay are made of gold and bitcoin so I decided to make my own.
They turned out well I think. They are not perfect, but not bad for a first go.
