#32 of 155 Using 93 and Car is PINGING!!!!! by micheleg68 Feb 06, 2006 (3:21 pm)
Hello fellow HHR owners, 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??????

Replying to: micheleg68 (Feb 06, 2006 4:21 pm) Do you have the 2.4L or 2.2L, Chevy recommends premium for the 2.4L, not the 2.2L. I have the 2.4L & even with 87 octane have not heard any pinging....even at 115mph. Are you in a hot climate or cold? Since my 2.4L doesn't ping even on 87,octane...and yours still pings on 93...take it in..something is wrong....I own another car with the 2.2L it never pings...If you're driving a stick shift & keeping it in 5th gear at slow speeds....or starting out in 3rd from a stop....that might sound like pinging...(or if yours has XM radio...take it off that channel you're listening to).

Replying to: smogdung (Feb 06, 2006 7:18 pm) Thanks for the reply, I have the 2.4L Bigger engine as well. I live in CT and its neither really hot or really cold right now. I usually keep the car in the garage at night. I was getting concerned that i may need to call the dealer,since all the other people have used the lower grade fuel and no pings. I think Ill call the dealer tomorrow!!!!!

Replying to: micheleg68 (Feb 06, 2006 8:28 pm) It sounds like it pings consistently so the dealer can hear if they don't believe you. Sometimes pinging is elusive.

Replying to: micheleg68 (Feb 06, 2006 8:28 pm) The 2001 RAV4 that we traded in ....it had VVT just like the 2.4L HHRs....we went thru an episode of pinging...lucky it was still under warranty....Toyota kept it for about 2 weeks (they gave us a loaner)....every time I would stop by the Toyota dealership there was a mechanic with his face in the engine ....engine laid open like open heart surgery... If I would have had to pay for everything that went wrong (from day ONE)...with that Toyota it would have cost me about $6,000 !!!! Hopefully yours is just a simple adjustment.

Replying to: micheleg68 (Feb 06, 2006 8:28 pm) Hello All, Its Michele,Well i called the dealer and explained the pinging and they said it is probably the fuel injector and the FI on these cars are known to tick. My husband explained to them that it pings ALOT... I may still have them look at it. Replies to this message: smogdung (Feb 09, 2006 6:27 pm) jerrywimer (Feb 10, 2006 8:35 am)

Replying to: micheleg68 (Feb 09, 2006 3:32 pm) That's a new one on me....a pinging FI ???? Let us know how it turns out. We bought ours on Nov. 28th...got a Red Tag Price + about $1,000 GM card discount...good trade in , etc. Just got a letter from GM Card...they will bump my $100 current rebate on the card to $2,000 if I buy a new car by 3/31. Humm, maybe I'll try to trade up to leather-spoiler & sunroof..... Replies to this message: jerrywimer (Feb 10, 2006 8:35 am)

Replying to: smogdung (Feb 09, 2006 6:27 pm) It depends on how the noise was described to the service person. Fuel injectors do make a 'ticking' sort of noise that sounds to me a little bit like lifters or something. It's definitely not the same as the noise I hear when an engine 'pings' (spark-knock).   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.
