He changed the ECU; still same problem (he told me he thought the Ecu was a culprit/Wrong again). I bought a set of injectors on Ebay (did not replace them though). I will get them cleaned and balanced later on.

While changing the spark plugs, I noticed that the ones on the rear cylinder bank were not screwed in properly (literally loose) . I am going at it, step by step. I am looking at the vacuum hoses as a culprit. The AFM area looks clean, I am still going to clean it before putting it all back together.

Once I am done, I am going to take it to get checked if I get a CEL, and take it from there.

Wow -- you've got quite the onion to peel there! Keep us posted, and good luck!
