I couldn’t as I am in the middle of the road when it stalls with just 10mins to conduct the test.
Anyway, I swapped with the aftermarket Dizzy - limited testing looks good. Should know in about 3 days. I also want to fix the original Dizzy with the parts I have. Thanks for reminding the PB Blaster.
With the aftermarket Dizzy, car runs fine.
I also noticed a screw from the Igniter wire was loose - unsure if its the loose screw or the igniter caused it. I do not know of a way to test without installing it? But it always started at cold - if it were the loose screw, then once in a while cold starting would have been an issue too right?
Besides a good m/c told me right away that it was the igniter.
Also there are others who had a negative electrical test on the igniter that was giving them misfire. But when they replaced the igniter, the misfire was resolved. So it is tricky.
Thanks all for your help in troubleshooting this.
