IAC help
I am getting a service IAC on rain days. Idle jumps to 1200 RPM. When weather clears light goes back out. Are there any moisture problems with this year? Does the IAC tend to go bad? Hate to change IAC and find out it was not the problem.
A week or two ago it did this the sun came out and I cleaned the throttle body somewhat and the code cleared and was fine until Sat in the rain again.
2003 CTS
3.2 engine
5 speed standard shift
90,000 miles

No codes
service idle control on DIC
was 1000RPM idle
today still no codes
idle went back to normal 650RPM
Have no idea what to look for.
