Ever since its been very cold, I get a weird noise when I start the car in the morning. When it is cold, I get a knocking sound on the driver side of the engine, below the intake manifold. This only happen when the car is cold, and the idle is sitting at 600 rpm. As I rev the engine a little bit the sound goes away and when the idle settle. The sound comes back, until the car warms up to normal temperature. The sound is like a rod is knocking, I have no codes, or any cel. Anyone else have this issue? I did some search, and did not find a clear answer. The car drives perfect with no issues. Any help would be great, thanks!
