I have a 2015 Chevy Silverado 1500 and I replaced my injectors yesterday. In idle there’s no knocking noise but when I start to drive it’s makes a loud knocking noise but once I get up to around 40 mph I can’t hear the knocking anymore. I’ve looked all over online but the only thing I see is from diesel trucks. Now for diesels I know injectors knocking after replacement is normal and will eventually go away. Is that the same for gasoline injector replacement?
