After installing the radiator and running the engine, it was idling very poorly. I had adjusted the valve lash and points gap, installed a stock air filter (ditching the K&N). The plugs were soaked with gasoline, indicating either weak spark or a fuel control problem.
I spent a few days chasing the possibility of an ignition bug, after breaking a plug wire and trying to set the points gap back to how I found it. Upgrading to electronic ignition eliminated the points and condenser, and the plugs were still fowling with gas. I put the K&N back on, which was no help. I was beginning to think that I had somehow messed-up the valve adjustment.
Yesterday, instead of pulling the valve cover to recheck my adjustments, I made a quick inspection around the engine. I had (previously) noticed a couple of wires that were too close to the exhaust manifold and tied them away. I checked those wires and found that I had broken one of them. They provide a variable resistance signal to the fuel injection computer which it uses to determine engine temperature to adjust the length of time the injectors stay open. Bingo!

| The car runs great now, but it looks like the test drive might have to wait. :-( |
