Good starting points. Also MAF voltage and condition of maf could effect this as well as vacuum leaks. Good luck!

thanks! First nice day we have I'll go through this mini checklist. IIRC I last checked the fuel pressure after the SR swap and it was on spot. It could have been with the KA though, I really can't remember lifes timeline lol
