Hello alm001,
first thanks for answering my questions.
So it seems that the sparks are pretty new and that the car didn't sit for a longer time.
Why did i ask for sitting for a longer time: i had a motorcyle with carburettors that was sitting for 8 years. I started it and it run well, but had some problems with upper revs. I dismatled the carburettors and found a kind of gumming (Verharzung is the german term for that) all over. It looked like a breaking up clear code on a car. This harnish clogged everything and that is why the bike didn't run well at higher revs.
So if the car has sit for a longer time in the past that could cause problems by gumming.
So there are 3 ways fuel injectors can fail.
1. they can fail completely, but that would give us a dtc.
2. they can be clogged
3. they can leak
If they are clogged than the clyinder would run lean but in general you won't get misfire.
If they are leaking you will get missfire, because there is too much fuel in the cylinder or fuel in the cylinder when it had not to be there.
So, because you don't get a dtc and because you have misfire and because of the way the spark looks like i would say some of your fuel injectors are leaking.
And because that you only have driven 700 miles on the sparks i would say act fast and don't drive too much with the car.
My recommendation is to uninstall all fuel injectors and bring them to specialized workshop. They can check if the fuel amount is OK, if the way the injectors spray is correct (german term = Spritzbild) and if one or more of them are leaking. Maybe the bad ones can be rapaired, maybe they had to be replaced.
Hope that helps.
Regards
Markus
