After lots of work on the transmission, I now get the following "leak" codes. I noticed some sparking on the middle, left plug (between plug and block) also. I inspected the flex hose between block and MAF but could not find leaks. I also sprayed starter fluid and carb cleaner in all areas, but did not detect the typical signs.

Where should I start with the troubleshooting?

this is your misfire issue, you need to solve that first and see what codes are left. New plug wires.

Spark plug wire set: do you think the Duralast will do? Bosch are 4x the price!!!!

Duralast is the shittiest shit in the world. but i guess if i had to buy one duralast thing for my car, it would be spark plug wires. easy to replace / no consequences of failing.
