'76 2.0 FI, stock motor except for a Crane ignition. All engine parts are functioning properly, no vacuum leaks, motor does not run hot, 600 to 700 rpm idle, just passed CA smog easily today. The car runs perfectly EXCEPT for 3 to 5 seconds or more of "run on" after the ignition key is turned off. Dave D suggested unplugging the four pin connector on the relay board in the engine bay at shutdown to see what happens (it powers the FI). I did that experiment and it stopped the engine "run on" instantly. That would suggest that the FI is getting power somehow after the ignition switch is off, right? What does anyone think I should try next to narrow down the source of the problem? (BTW, DaveD does not recommend a diode on the alternator light wire, could adversely effect charging, and I would prefer to find the actual problem too). Any ideas?
