pingpingpingping
not a fun sound! on light throttle openings going up a grade or full throttle/high rpms going up a grade, 87 pings like a mother even in this mild weather. 89 is managable but i can still get it to ping if i want to. its been doing this for a little while but i wanted to be sure i didn't get a bunk tank of gas.
no CEL, so my knock sensor isn't bad. after researching it seems like this isn't a totally isolated incident. some subies were equipped from the factory with trashy champion brand plugs, which after 30k will probably be pretty demolished. i might also be pulling oil into the engine if the PCV is junk which of course doesn't help my octane ratings.
these are 30k mile maintenance items anyhow, which works out because i won't go to the dealer for a raping on easy replacement items like these anyway. so i'm hoping i'm just experiencing wear on these parts. if it doesn't help i will be going to the dealer, however.
