Hey all. 2006 GMC Yukon XL here. A few days ago I filled up Bertha with mid grade gas as I normally do. I get a knocking in the engine if I used regular unleaded when I have to put the pedal down hard. Anyway! I didn’t fill it up, but about 3/4 tank. I had a ticking sound immediately at idle, that increased with speed. No warning lights on dash. Oil level is great. On the way home it simply disappeared. For days.
Just now I got gas at the same station and it immediately did the same thing, for about ten to fifteen minutes, then went away. What gives? Anyone else encounter this mystery?
TIA for any suggestions.
