scion tc 2008 knocking noise coming from engine while idling and when driving the same speed. when i accellerate a little bit it goes faster untill i reach about 3000 rpms then it goes away if im punching the gas pedal. if i let off the gas and coast you cant hear it.

check your oil level to make sure it's full then have a pro listen to it so you can see if it'a valve train part or somethingmore internal. i'd do it as soon as you could
