If most you guys have replaced the IACV and seemed to fix your " high idle " cold start problems then thats great !!! HOWEVER if you, like me, replaced your IACV and still the problem persist then try this !!.
1. Remove all Intake arm from Throttle body to air filter ( more room to move)
No Pic.
2. Locate the the Throttle Body and find the hose shown in this picture.
3. Once the car has been started for at least 2-5 mins feel the hose pictured and it should start getting warm, coolant should be running through this .. IF ITS NOT WARM THEN BINGO THERE'S YOUR PROBLEM !! A BLOCKAGE.
4. Remove the "helmet" shaped housing which the hose connects to on the side of the Throttle body which from memory is held on buy two bolts/screws.
5. Mine was all rusted up and gave it a good clean out with TB cleaner and wire brush ( DO THE SAME !! )
6. Seal it all back up with some gasket glue
7. Connect all hoses and pipes again and start her up and..
BINGO !!! Pipe is now warm and has coolant running through it which now engages the IACV PROPERLY !!!
Particular usefull for cars with high kms or imported motors...
