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.

Do you
have the same problem?

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
