Well I sold my type R last night on Ebay for $19,100.00. I want to fix one minor thing before I send the car to the buyer. After driving my car for about ten minutes when I pull up to a stoplight and the motor idles, it fluctuates from 1k to 1.5k really fast, it sounds like I have some mean cams. When I turn the car off, and restart it, it goes away for awhile but then comes back. What could this be? I unplugged my IAC connection while it was having this rough idle and it went away. Could the IAC motor be bad?

 

IAC would be my guess.. that was my guess from the title of the post actually.

 

check all your vacuum hose connections, could be due to a leak...the IACV valve can go bad...well best wishes and sorry to see your R go, hope she goes to a loving home...ERic
