Default Cleaned IACV - Parts Fell Out?


Pretty confident I found my stalling issue. Opened up the motor side and these two shims fell out, any idea how they go back in? Also, what oil should I use for the bearing. Thanks!

I did this a few months ago. This video at 1:57 shows where the shims go back (good thing you didn't loose them!)


For the bearing oil use sewing machine oil, or any very thin oil. I would also highly recommend replacing that rubber gasket. The video I linked above was a huge help for me.

Do you have to bleed the coolant after doing this? Always wondered..

Nice, thanks! I will bleed my coolant I am sure it creates an air bubble, and air pockets and Hondas seem to go together.

This solved my problem. Symptoms:

Once the warm-up idle cycle was completed, the car would bog and have trouble trying to find idle, especially when revving down. When it did it would have a very low idle and shudder. This was most notable when pulling in to a parking space, the car would basically just shut off as soon as it was stopped.

Nice! I had very similar symptoms and this resolved it. You don't have to bleed the coolant, I asked the same questions and found my answer here:

I also took apart and cleaned the throttle body channel that runs from the MAP sensor. My stuttering and almost stalling is completely gone.
