IAC

[#2875]

i have had my IAC out several times to clean. is there any way to test to see if it is functioning properly while it's out? mine doesn't move very much at all. maybe .02"-.03". is this normal? shouldn't it be springy????

Test it while its in the vehicle.....

You can check it
out by connecting the A&B terminal on your ALDL connector with the ignition
in the OFF position (located under dash drivers side) turn key to the run
position (do NOT start engine) go out to the IAC it will make a slight
growling noise when bottomed out. Now disconnect the IAC and start your
engine set the idle to 650 rpm if it isn't there already. If the Idle has
never been adjusted before you will need to remove the plug covering it. Re
connect the IAC and put the trans in gear the idle should quickly go to the
set RPM.


Or buy one of these fancy gizmo's if you have nothing else to spend money on....
