I have been having problems with the IAC valve so on Sunday I took it out and cleaned it. That didn't work so I replaced it. The car idles perfectly but for some reason the check engine light came on. Checked it out and it came up as a code 32. The thing is, I just replaced the EGR valve 6 months ago amd the car still runs like it is new. Any thoughts or suggestions?

 

I had the same issue but only came on at freeway speeds. I too changed the valve etc. but mine turned out to be the EGR solonoid mounted to the coil bracket.

 

Never mind I found the problem. When I put the throttle body back on I missed a vacuum line on the bottom of it.
