First sorry if this has already been posted .. i looked around and didn,t see anything and second .. i'm from Quebec so my english is not excellent .. i'll try to explain as best as i can

I got a 06 TL with 95 000 km on.
I got it 3 months ago so i just noticed that.
When i'm on the idle .. on the park but not running .. it seems like it's knocking .. it gives little knocks .. nothing big but enough to feel it when you're in the driver's seat ... in french " ça donne des p'tits coups"
I thing it might be the sparkplugs but before changing it i just want to be sure ... i'll check at the garage when i'll put my summer's tires on but just wanted to check with you since i'm still on warantee.
Thanks !

 

not sure if this helps. i have an 08 tl....i hear the same small knocking sounds on idle.....took it in to acura, they said it was the fuel injectors working. But to keep me happy they called out a tech and he "stuck hes ear in the engine" stood there for a while....then said sounds like a tension belt.

 

BlackPearlAngel: How would spark plugs make a knocking noise??? Are you sure it isn't valve tick? Here are threads talking about valve train noise: https://acurazine.com/forums/showthread.php?p=12653820

I have a similar tick/knock noise, at first i thought it was rod knock but quickly figured it for valve tick. The last time i have rod knock, on another car, the motor died fairly quickly.
