Hello i have a 94 honda civic ex coupe, My idle keeps hunting and tuning it with the screw doesn't seem to do anything until i get it too low where the car is going too stall, Any ideas on how to fix this an keep in mind i am not very mechanically inclined.

 

CEL codes?

Did you bleed the cooling system and clean the IACV?

Then follow service manual to adjust the idle speed. There's more to it than turning the idle adjust screw.

 

Could be a bad o2 sensor too
