APR adjustment and check engine light

[mazzo]

Hi all,

I keep getting check engine light when I going uphill (code 1222) when my FPR is adjusted to 3.0 bar. But if I pump it up to 3.5 bar then problem solved. However this is a band-aid solution as I don't want to run rich and screw up my cat. I am suspecting my AFM is acting up but not sure (I plan to take it out and clean it up soon). But other than this any idea what could when wrong? Thanks!

Sorry, it's FPR, not APR...

Could be dirty injectors

What Injectors are you using ?

19lbs injecors. I am running it with SSSquid and M30 AFM. Been using this setup for over 2 years. No check engine light and just passed smog last week with flying color.
I also start to think could it be my AFM needs clean up, because if reading from AFM is not right it would think I need less fuel than I really need to. Well, just a wild guess...
