Spark Knock or engine ping?
my 2001 Lexus now has 201K on it. Yesterday, after I filled gas, it developed such noise. I am not sure if it is because of gas, or the car has other issue?
Could any one help me to listen what is the noise? No check engine light yet. The sound frequency is positively correlated with gas. The harder I push the gas, the higher frequency the noise is, and louder.
[Update] I captured a new video in the garage. The noise is significant in door. (there may contains some tire slip noise in the video)
Sorry, it was too late to capture this video. I will capture another tomorrow.
