ah ok so under load only when i accel hard i hear metal knocking around... i am a auto tech with like a year exp.. i have never heard this before... doesnt make noises at a standing rev.. on heavy load.. is it the vvt, or cam chains, or pressure plate???? any ideas? i am entirely lost, you can treat the problem, i thought about changing tensioners, but dont wanna be a parts changer!

 

Your pinging... what octane gas you using?

 

91 best i can get.. definately not a ping.. like i said i am a tech.. i know what a ping is.. its like some chain or metal on metal hard sound.. like a chain gettin dragged on a metal ledge. best i can describe it
