Attention: TDR Forum Junkies As my truck is idleing. I can periodically hear a knock or pinging noise. It has a constant beet like its a cylinder knocking. However, it's speratic when it is heard, and it doesn't always sound like the same cylinder. This happens when the engine is at operating temp. I changed the place where I buy fuel and it's seemed to be quieter, but still does it. It's not that loud, but is still there, and noticable by others. Is this part of the noise that could be an ejector that everyone is talking about? Could this be blended fuel? I don't rcall hearing this during the warmer months. I seem to recall a thread were someone had a sound bite of their truck that had a knock.
any thoughts?
