In a nutshell, there are no ISTA errors/codes now. The car idles rough (seems to be missing), particularly at approx 900rpm. Higher in the rev range it isn't as bad.
Does seem low, but if you were off time, you would prob get 0 compression. So that kinda a +. No idea on the flex plate, ours cranked but did not even try to start.

What timing kit did you use? A good one or a cheap fleabay knock off?

It probably needs to run for longer to get more codes, but thats kinda not a good idea.

You did pull the injector plugs at the same time, yeah? Otherwise you should prob change that oil, put a couple of drops into the cylinders.
