So I've had this truck for a couple of years and the other day, I'm driving down the highway and I get loss of power rough idle and codes for lean condition and misfire cylinder 3.
I pop the hood and see this.
I could've sworn there was a plug or something in there. Stuffing it with a rag causes the idle to smooth out and power seems to come back. Pull the rag, and it immediately stumbles and shakes.
Is there a good way to fix this that doesn't involve replacing the air tube?
