IACV GASKET

[AU Qx4]

Does anyone know if you pull the IACV to clean and change gasket, will you have to do a idle relearn?

Car runs great but at 155,000 mi, I think it would be wise to change the gasket.

Very wise (save having to repair the ECU), mine broke into hard pieces when I removed it with less miles. No, I did not have to do a idle relearn. Take the opportunity to thoroughly clean the throttle body with a tooth brush and q-tips dipped into throttle body cleaner (I used the small cap from the cleaner can.)

Thanks Alan, good advice!

Just changed the IACV gasket. Mine was in pretty good shape, not too much carbon build up either. I broke the old gasket in one spot picking it out but didn’t seem too brittle surprisingly. I would post some pictures butI don’t think attachments are enabled.

I am taking this truck from Florida to Yellowstone to Grand Canyon to New Orleans etc. about 6300 mi total so I am getting out in front of every known problem before I go. Changed tons of parts already, with more to come.
