So I pulled off my intake manifold to check and see if my red check valve had failed and to my surprise it was intact. So I cleaned the manifold and out everything back together, I drive it for like 15 minutes and a get a check engine light with the p0033 code. To no avail I can not pin point what could cause it. I seen a video on YouTube and the guy said it could have thrown a code because I had unplugged alot of sensors during the take apart. Tomorrow I will clear the code and see if he comes back. Has anyone encountered this code before?

Yes unfortunately it expired at 90k miles. I think it's the pcv hose that runs to the top of the manifold. Going to buy a new hose and clear the code and see if that is the problem. They thing is. My car isn't idling sporadic anymore or jeering on acceleration since I pulled the intake manifold off and cleaned it.
