So since this post I’ve had the issue pop up maybe 4-5 times. The check engine stayed on for awhile but now is off most of the time. Yesterday I got new tires due to another issue I’ve been dealing with and ask a tech how much change the spark plugs. He took the plastic cover off the manifold and I noticed at the right of it was a small hose coming from that plastic piece I believe you mentioned ( in the picture). The hose looks kind of melted, cracked and is very loose. I can’t seem to find a diagram to tell me what it’s called so I can price/replace it.
