Carbon cleaning may help. Most of my miles are on the highway so it took longer to develop issues (erratic idle at times, mild hesitation). Carbon cleaning made a world of difference on how the engine runs throughout RPM range and load. When I did my carbon cleaning of the intakes, #6 was the "wettest" of the intakes. Other than that, have you replaced the PCV? Have you had the oil analyzed, indicating possible fuel contamination? You said you swapped injectors, so the problem should have moved with it. t
