Default 2008 chevy equinox ls 3.4l

I've just completed new head gaskets on mu suv. It runs fine except the idle is running about 1300 to 1800 rpm after it warms up. when it's cold it's about 750 rpm. I've checked for vacumn leaks with carb cleaner both when it's cold and hot. Any Ideas?

is the check engine light on?
go back over what you disconnected vacuum hose wise and see if anything is cracked or not fully connected.

ok. Thanks, I'll check it out. The engine light comes on sometimes but not always. I think I have to get the throttle body reset.

HI, I found out it messes up the idle when you clean the throttle body, but it will reset itself over time. MIne has done that and is good now.
Thanks
