Couldn't figure out why my b18c wasn't running in my eg, (computer was p72obd2 engine was obd2).

Buddy (mechanic) adjusted the IAC to get it running just to my house (was bogging, idleing horribly) but got it there.
(Bought a obd1 p72ecu - but car has slightly odd idle)

How do i adjust this back to the proper setting ? -

Do i take off the throttle cable? etc.
I found the screw with Yellow paint on it on the side of the throttle body - Do i turn counter clockwise with a screw driver?

 

Your IACV (Idle Air Control Valve) should be on the back side of the intake manifold. Theres something on it in the FAQ's that will really help. Takes you step by step. https://honda-tech.com/forums/acura-integra-6/%2A%2A%2Ahow-clean%2A%2A%2A-your-iacv-k-idle-air-control-valve-1575913/ That is the link there

 

Don't turn any screws until you know what you are doing. Judging by the description you provided, you don't know the difference between the IACV/EACV and the throttle body.
