Just trying to find out if there is a setting on the throttle butterfly that u set just to allow air in on tickover or is it just closed ??? having trouble with C/O so going back to basics

 

you can ajust the idle screw under the butterfly which basically does that and lets more air though - but as a result does increaser the idle speed - as you'd expect. you can ajust the cable to actually hold the butterfly open but his isnt recommended, i think what you need to do is ajust the CO ajustment screw on the ecu, it s small pot that can be ajusted to do exactly what you want
