Hey Guys,
My car has recently started making a knocking noise while in drive stopped at the traffic lights. It doesn't always happen, only when the car has warmed up, in drive and stopped - even still it the knocking noise doesn't always come on maybe 8 out of 10 stops. The knocking sound goes away when I start moving from the lights or when I put the car into neutral.
I drive an 07 Liberty GT Auto with dump & mid pipes, 3 port, and tune.
Any ideas what this could be? I'm rather concerned.
I also have a weird whining noise which i'm sure isn't induction or spool. it comes on when I step on the throttle half way.
Any advice would be greatly appreciated!
