I have read alot of the posts on pinging and i have a problem. I bought the car in mid January brand new and it was pinging the next day. That week i put in 89 octane and i didnt think anything of it, then when i kept hearing it i thought my hubby read that you need to do premium, so next 2 fill ups i put 93 hoping the pinging would go away and it hasnt. i dont notice it at stop lights, but say like at DDonuts its very noticable......... i thought maybe the low gas had to be used up to not hear the ping, but that was 3 weeks ago!!!!!!! im wondering if i should call the dealer or not. im not noticing any bad mileage or anything but it worries me.. any thoughts??????

Injector noise occurs as they actually fire and is usually only audible at very low speeds or at idle, many times in situations where the vehicle is running near a sound-reflective wall (like in a fast food drive through). My Silverado 5.3l does this at McD's. At driving speeds they are inaudible, completely covered over by all other normal sounds (wind, road noise, radio, etc.).
Pinging on the other hand normally only happens when the engine is under load, like when climbing inclines or during rapid acceleration. That's because the detonation usually occurs when the motor is straining. I don't know if it's still considered normal for cars to sometimes 'ping' under extreme situations, but it used to be. I remember some older manuals mentioning it in the 'fuels' section, and saying that some pinging in such situations was normal, but that if it occurs in regular driving that either higher octane gas should be used (than the minimum recommended) or that the vehicle should be taken in for service.
Thanks. :confuse:
If you don't mind me asking, what is the name of your dealership and city that's it? My dealership replaced the theft deterrent module and the issue is still there. I was hoping they(dealerships) would be able to communicate and come up with something since GM has no clue what the problem is. Was it the main computer they replaced? Or one of the others? :confuse:
lemon laws start with the dealership first.....
Turn off motor and depress the brake pedal repetedly is what broke mine in the first place. I was not attempting to break anything only activating the brake lights with key off. 26000K Miles
I took mine to Rotolo of Fontana. I am very impressed with their overall level of customer care!
