No codes, running like crap

Runs poorly or not at all. No codes showing. One injector is weeping. Did find a burnt connection for the fan.
Any suggestions.

Need a lot more information if you want us to help. Define poorly or not at all. When?

Bogs downs. Rough idling. Between 8500 and 9500 rpm...jumping up and down. Remember no codes during any of this.
Changed the fuel filter.
Cleaned the injectors
Used throttle body cleaner.

So, you know one of your injectors is leaking. I'm sure that's not helping your truck run, any. You'll need to fix any known problems first.

Also, check your fuel pressure

What is the make, model, and year of the vehicle please? It does make a difference.
