Hey guys, just started experiencing this problem today. Only thing I've done to the car since it started was cleaning the interior. Went to the shop today and I guess as the car warmed up I stopped at the lights and my idle started slowly decreasing until it died. Turned it back on and kept driving. Was fine for like 2 stops then got home in the garage and same thing happened.

So far I've cleaned out the intake and TB as well as the maf sensor. Does this sound like a bad oxygen sensor? When I removed it a while ago I used WD-40 to loosen it up and I'm thinking this might have damaged it. I have no check engine light btw. When I accelerate in neutral and keep it steady at certain revs it will just decrease slowly on its own. As I was driving I got up to 3k revs and it lacked a lot of power, it kinda just sat at 3k revs for a bit before increasing again.
