Sounds like restricted fuel delivery or weak spark. You need to check your fuel pressure at idle and fuel flow(harder to do). If anything, remove your fuel pump and inspect its filter and other related components that attach to that assembly.

Could you please list the manufacturers of each part that you replaced, and who did the labor?

 

all denso/oem parts doing the labor myself. replaced the tps and removed the ful pump and cleaned the built in filter with no change. took a better video

Oil control valve should be in your list also. Typical issue for the first generation of VVT-i engines.

 

i think i'm looking in th wrong direction all together wouldn't all these senors trip codes if they were bad? could there be something bad mechanically that won't show up on the obd scanner?
