Guys I really am not sure what to try now, I'm going to try making the vacuum/boost leak tester to see if I really have a vacuum leak but it seems backwards. Wouldn't I run lean at low rpm and rich at higher rpm?
I've already replaced all the gaskets/vacuum lines and cleaned out the IACV. If I can't figure it out soon, I'm just going to do every semi reasonable thing in one shot. Replace every line in sight, try to source every hose possible, replace the IACV, Knock sensor, temp sensor, and maf.
Any other ideas? I just want my car back
any chance it could be my ECU?
Thank you
