I guess my earlier posted got deleted somehow. I was just wondering if I should take my 200 duratech atx 30k miles back to the dealer for this faint pinging. I have no CELs and it drives fine. Backgroud: just recently developed this faint rattling sound when puting some throttle while cruising in OD at around 2K-3K on the tach. It goes away when the atx decides to downshift. Engine temp is normal and it is in the 60s here.
I took your advice.. 93 octane, 1 bottle techron fuel system cleaner and clean the MAF sensor (possible over oiling of K&N).
It is till there and it has been a week. I guess no one would notice this sound except me since I have a discerning ear for strange sounds that come from my car.
So should I 1) take it to the dealer and ***** to them about the sound? 2) Wait till a CEL pops up and then go? 3)Wait for it to go away or ignore it?
