While I'm able take care of most maintenance and other work on my car myself, I am admittedly not very good with engine mechanics. When I am under medium to heavy acceleration I sometimes get a metallic "rattle" that sounds like it's coming from the engine bay, actually more under the car. It's pretty subtle but I can usually hear it.

Is this pinging?

 

a little over 11K on my 08 and no pinging (yet?)

 

08 Type S... and not that i know of...

 

08 TL-S with 3200 miles. I haven't noticed any pinging but then again I haven't listened for it. I'll have to check it out. Thanks

 

08 TL-S with ~1800 miles and no pinging that I know of

 

08 TL-S with a little over 3k miles, no pinging.

 

08 with 700 miles. No ping!

 

mine pings just as my 04 did... i have learned to live with it

 

what does a ping sound like? how would i figure out if my car pings, i have never taken it over 3k rpm so do i have to rev it harder to find out, i am at 25k miles ... 93 octane

 

08 with 1500 miles no pinging

 

i dont think my car pings...

i havent really noticed any "Valve chatter" cruising or accelerating hard.

i got a CAI on it and anything above 4k rpms alll you can hear is intake.

it did throw a CEL light a few months ago for System too Lean.
came on here and searched the code it threw. and a lot of people said it was bad gas. so i immediately went and filled the tank with sunoco 93, light went away.

the CEL came on with a no name brand gas i got from a station i dont really go to unless i have to. never went back there, cel has not come one since


i got about 7200 miles on my 2008 TLS 6MT

ill try to pay more attention.

i use 92 octane from Wawa, and 93 Octane from Lukoil and Sunoco.

 

if your on a hill and in a high gear wot, you should hear it chatter... i wouldn't do it for long, but it might be a for sure way to hear it, and notice the sound...

 

Mine is an '08 Type S with 7k miles. It pings expecially accelerating uphill around 3-4k RPMs.

 

no pinging on my 07 type s auto, 10k miles and i use both mid and premium gas which is 89/91 octane......

 

I dont own a TL. But when I went to my Acura dealer a couple months ago, I asked them if they put premium fuel in their cars. I was shocked when they said no. They said they put regular in all their cars. I wouldn't be surprised if other dealers were they same way. This may be the cause of the pinging you heard while test driving.

 

'08 TL-S, bought about 2 weeks ago, put on 1800 miles of hwy driving. The car did not ping/chatter when I bought it (or i just didn't notice it). The car does seem to ping/chatter when at idle, and it does get a little louder after miles, I believe this to be break-in on the engine/etc... but under normal driving conditions/acceleration/anything above idle it is fine. I am guessing they are ideling the engine really low to save gas... so it might ping/chatter a little... I might try a thicker/heavier oil at next oil change to see if it helps with this problem. I don't have to worry about winter temps because I am in florida so a thicker/heavier oil should not be too much of a problem for me.

 

You're hearing injector/valvetrain noise which is normal. It's pretty much impossible to ping at idle. The noise doesn't hurt anything but going with a good 30wt oil reduced my noise by about half. All I hear now is the click from the injectors but otherwise the engine is super smooth and quiet. Again, I didn't go with a thicker oil to address the noise but rather I feel a 30wt is much more suited to my hot climate.

 

im using amsoil 5w30 synthetic motor oil in the pup also. dunno if that made any differnce or helped with noises and or ping ping pong pongs
