Thread: What Air/Fuel ratios do you see at idle?

well yesterday i cleaned my

AAC VALVE
Sprayed carb cleaner in the IACV tube
Cleaned PCV valve
Cleaned throttle body

and now my idle and air fuel ratios with the idle screw screwed in is fluctuating now. it is like 15.x-16.x maybe sometimes high 14s at idle, but the idle seems to be idle hunting now, so i think i mgiht have to pull the iacv completely off and clean it

Maybe you should reset the ECU. Then let it will self learn and it might fix it self.

well im running aem ems so its a little more complex that that.

i think my Air regulator might be clogged
