Hello. Could someone please tell me how to install a new throttle body in my 2008 CTS DI. I heard that the job is pretty easy and only requires a few steps. I’m trying to avoid taking it to the shop. I ordered a new acdelco tb. Will I need a new gasket? Thanks!

I took a quick browse through ALLDATA. Did not find the full install instructions, but did find that there is a throttle position "learn" required after install. If you have idle issues after your install, that is likely the reason and you will need to run the procedure.
You should get a gasket with it. It is a very simple thing to replace and should be able to figure it out without asking on here.
You will want to disconnect the battery negative terminal to insure the car won't automatically try to start for some reason, take off the air intake hose, unbolt the old unit and unplug the wires, bolt the new one on with new gasket, connect wires, connect intake and done. Just make sure when you tighten the bolts you try to keep them all the same torque but its nothing major.
There is a relearn procedure but when I did mine I just hooked the battery back up and let it do its thing.

I would always use a new gasket whenever I replace something where a gasket is involved. Cheap insurance and you only need to do your particular replacement once.
