i think i get the same problem. the dealer said they were pinging sounds under acceleration, i can only hear it on a quiet street with the window down. they told me to put higher grade gas in.
I use 91 one and i don't hear that sound anymore when i have only myself in the car.
when there are 4 ppl in the car and i accelerate i hear that sound again.
so i really don't know what i can do... wait for the car to break down??

so i have been having problems with my car pinging under exceleration, i used some cleaner that went into the vaccum hose it helped a little .. but now its back and even worse. If i put 91 oct fuel in my car it helps a little, but its starting to get expensive. The car pings like crazy!! and on top of that when i come to a stop my idle drops so low the car shakes and almost stalls, and the oil pressure light starts flickering like crazy...anyone know whats causing this??(help)

Check Oil Level as soon as the light comes on... Anytime! The light is a "Already Too Late Indicator"

Ohhh, brain fart. Gas is being switched over to "winter blend" MEaning 87 octane is actually like 84, 89 is like 86 and 93 is 90 or lower.

Umm, Winter Gas... I live in Canada and I have never heard of this s***. ****, We invented Winter...
