Changed spark plus got two errors, one fixed

So I replaced my spark plugs with recommends NGK ones.

Cleaned out my vanos solenoids, and cleaned the MAF.

Started the car and it's running rough, I could tell it was all cylinders.

So I plug ISTA in run the scan it reports he usual anti trap protection stuff etc. Ride height sensor. All the same stuff I've seen before.

So I plugged in a generic OBD scanner and it read P0306 and P1017.

So I turned the car off, traced my steps back and noticed as apparently P0306 is cylinder 6.

Find that the connector at this cylinder wasn't all the way in. So I fix that and figure this is my issue for sure, check all the other connectors, check to make sure the plugs are nice and tight.

Turn the car on and it's running better. Actually seems to run as usual.

However check engine light is still on. I can't can't clear the error with my generic OBD still the same errors by the way.

Am I doing something wrong in ISTA not being able to see these and clear them?

See the screenshot for errors..

Alright to provide an update.

Checked all spark plugs, coils and connectors. #6 connector was not on properly os this immediately fixed my running rough/weak problem.

However I still had the check engine code. So I did searching online on this eccentric shaft sensor.. took it of to inspect it all looks good. I never touched it so I was surprised it was acting up.

So took the car for a drive and it runs fine, power is there. CEL is on.

Then it clicked.. sometimes to clear codes the car shouldn't be running but in position 2 key.. so I tried that and the generic OBD read the codes and cleared them no issues (previously it was spitting out fail but the car was running).

Started ar, no lights on. Runs fine as before. Went around the block and all appears good. Ran the scan now with my tool and it spits out P1017 pending. Now I can't say this code is due to my work I did this evening or if it has been on the car before cause I never used this generic scanner on it. I did pop the eccentric shaft sensor off and the pins appear somewhat oily.. I know the PO had the valve cover gasket done previously on this car.

Which now leads me to my question, why is ISTA no reporting these two issues and why is the DME erroring out? Should the car not be running when scanning with ISTA? But in position 2?
