hi bud, I read some of your post and I understand you are more expert about car mechanics than me so I have a quick question for you. You know the engine ping issue 2Gen TSX had I still have that issue despite the fact I have done the TSB replaced knock sensors and update AT. I can still hear a slight ping around specific RPM's at really high RPM I can't hear nothing and I do use higher octane gas since day 1 and still did not see the ping noise go away I love this car but when that ping noise comes I get soo upset. So what you think I should do? your technical opinion is greatly appreciated bud
