A-b ... A
5 times a charm! 5 cold starts with no probs, using the Firefly's coil.
I'm going to swap the Metro's coil back on tomorrow and see what happens for the next 5.
But I think that's got to be it (touching wood).

Cool. "Known good & free" parts make great diagnostic tools, haha! Looking forward to the return of bucking and stalling when the old coil returns to duty. Then we know!

It just wanted some love and attention. She'll be fine if you treat her right.

I think Stubby might be right: I put the old coil back in and it fired right up. Just wanted some attention?
Intermittent problems are fun!
This is killing my tank average, too ... threatening my 70 MPG goal! SG said ~72 MPG when this nonsense started. Now it's 70.5
I should fill up now to lock it in. Put some of this silliness on the next tank.

Factory Ford troubleshooting has you install a known good part as one of their last steps on some of the diagnostic trees. This is great if you own a known good spare part.

But early in this thread I think you got the same results sometimes and then the problem returned a few starts down the line, no? with the "bad" coil, I would wait to see if it returns. Seems like it might.

Yes, definitely. Take that bummer off the list of bummers in trouble shooting.

Correct.

I'm hopeful.
One other thing I thought of: a simple run of cold starts might not be a valid test. I need to actually drive the car: heating the coil up might be part of the problem? I'll be using it again this weekend. (And I did have a couple of longer drives with the known good coil.)
For those still keeping track at home:
- Trouble-free cold starts on the Firefly's coil: 5/5
- Trouble-free cold starts since re-installing the Metro's coil: 2 (so far)

Done!
First kilotank (1k+ km = 620+ miles) in the beater Metro: 72 MPG US!

Have I mentioned yet how much I hate intermittent problems?

I’ve had two coils fail in my LSJ before I upgraded them, and I’ve had two coil packs fail on my L61, before swapping to the one I’m running now... the failures have always presented as a constant misfire though...
