I haven't touched the S-10 yet and I don't think I have time to do either of the big projects anymore. I'm fighting an issue on the S-10 right now where it keeps burning out the crank position sensor. It almost always happens on the freeway, pop a new one in and it will be good for 500 miles or so then it will start having issues. It usually starts with a little engine pinging while the tachometer will jump up 1000-2000RPM, it will do that a few times then run fine for the rest of the trip. It will start doing that more until the engine starts cutting out and eventually dies.
I can't replicate it sitting in the driveway yanking on cables, it only happens when the engine is warmed up (unless it gets really bad, it's only left me stranded once). A new sensor always fixes it and it runs perfect after replacing it. Unplugging and plugging the sensor back in doesn't fix it.
The problem has been occurring for a few years, as time goes on however, the interval between failures is getting shorter. The first time it failed, it did the weird pinging thing on the highway for 6 months before I finally figured out it was the CPS causing the issue, now it's down to a few hundred miles between failures.
Also, dragging the trailer around for camping has caused the frame to crack in new and exciting places so I have to fix that as well.
