Q: Knocking noise

asked by on January 10, 2017

When I first start my truck up on a cold morning, there is a very noticeable knocking noise. As it warms up it fades away. When I get in the cab and start driving it's noticeable. But it's worst when I first started in the morning. Is this a bad injector?

My car has 210 miles.
My car has an automatic transmission.
