Just Changed The Idle Air Control Valve Do I Need To Do Anything Else I Tried The Black Knob On The Side But It Didnt Seem To Bring The Idle Up Or Down Do I Need To Reset The Ecu Or Will It Be Ok

leave it alone mate. Get in the car and turn the air conditioning on.If the cars revs hold without the car stalling then it is working.
Hope this helps..

if it's not idling properly now try an ecu reset i recomend this when you make any changes makes the car behave so much better

I Done Reset It Followed Gk S Reset 2 Mins Ac On Off Etc Took It For A Half Hour Drive Seems To Be A Bit Worse Will It Take A While For The Ecu To Relearn Hope So

It idles crap because the base idle needs adjusting or there is some other fault. If you disconnect the battery on any Falcon for more than a few minutes and then it wont idle, then there is something wrong.

Give it another few days of driving and see how you go.

Perhaps it was the plugs, leads or perhaps even coilpack. In fact the leads on my wagon are being done tomorrow, and if no joy, then the coilpack also. Hope the leads do the trick though.

mine has had a bit of a rough idle since i got a flat batt.

i reckon if i clean the throttle body/isc and reset base idle it should be sweet. im just too lazy

Since we are on this topic, does anyone know what that black knob is there for?

It's to hold it when you take it off or put it on. The metal casing is very sensitive to fingerprints, and you shouldn't touch it when removing it, as it disturns the airfloe. The black knob is what you should use to pick it up with. j/k

No idea.

if your base idle has never been touched leave it alone is is not meant to be changed unless there have been major changes and what ever you do don't just screw it up or down trial and error style there is a precise method for setting the base idle. it involves getting the engine to operating temp (the fans have run then stoped )and with all accessories off and the wheels straight ahead stop the engine and dissconect the wire from the IAC valve insert a 0.75mm feller gague between the throtle stop screw and it corresponding tab connect an accurate tacho and start the enging. with the fans not running adjust the base idle to 700 RPM +or_ 20 RPM stop engine remove feeler gague and reconnect IAC valve start engine and rev to just over 2000 RPM to reset the IAC valve. of course this should only be done with the engine in good order with no other faults

If base idle is to be adjusted as directed by a self test then the above procedure should be carried out with the engine running in self test mode.
