H&s tuned cold starts Knocking and blowing???

[clutchdabomb22]

when i start my truck up it will do the normal high idle and after a couple minutes it will start knocking and blowing a ton a smoke like theres way to much fuel being supplied, Il turn it off, start it back up and its okay. The code it threw was cylinder 8 misfire? aany ideas, im a little hesitant to take it into dealer

If it does it more than once take it to the dealer. You don't want to play with a bad injector, you can melt the whole engine down like that.

I would take it to the dealership.

Please correct me if I am wrong, but wasn't there a tsb or recall on some 08 trucks regarding the injectors?

Yesss! and they replaced them already, thats why im worried.
