So this weekend I decided to fix the stupid EGR code I had for a few months. I removed my intake manifold, and cleaned the inside of it with the carb cleaner thing. Also cleaned with EGR pipe with that same stuff.
Everything was going well until I started the car and got a 02 05 code.
I checked all the sensors, and hoses to see if I had miss something, but everything is plugged in. I reset the code and so far it hasn't turned back on.
But my idle is acting weird. Sometimes it idles at 2k when is cold, and just normal idle is about 1k rpm, and it keeps bouncing from 1 to 1.2 to 900.
Not really sure what could be the problem now

 

Double check all the vacuum lines, make sure you don't have a leak near the TB or IACV gasket - did you use new gaskets?

Unplug an reconnect all the harnesses to the IACV - perhaps one of them hasn't quite "clicked" on properly.
