I got the soldering done today.

I didn't wreck the ECM when I replaced its biggest electrolytic, which might have been bad (it came apart when I was unsoldering it, pulled the cathode pin right out of the can). Car started and drove, and will get the hot test tomorrow.

I messed up one of the breakout sockets for the Pico W, soldering the screw connectors on one side into the wrong row. Doomed, but the other one is okay.

The current monitor assembly went ok, expedient and gangly but finished.

Didn't fix the problem: got a P1074: too lean, out of stoichiometric range.
Couldn't test the cap I replaced: destroyed it on extraction.

Car is nearly 30 years old, and the fuel filter has never been changed, so that's next. Supposedly easy. Isn't.

I'm going to try to do a rate test on the new filter, so I can compare it to the old filter. Exploit Poiseuille's law and test with something with a higher viscosity, like 50:1 oil, for a more sensitive measure of a possible filter problem.
