I'm getting ready to take it back

[osue077]

So about a year ago, i had a shop replace the injectors on my truck. I haven't driven it much since then but I also replaced the fuel pump since then because it was leaking. Recently when I start up my truck, I get a miss until it is warm but the engine still feels weak. Ocassionally while the truck is warm, the miss comes back but then goes away. The CEL light has not came on at all so what is everyones thought on this. The shop thinks that the valve cover wiring harness is the problem but I'm not too sure. To me it seems like a blocked injector possibly. There is no white smoke associated with the miss is why I am thinking injector. When I take it in, I just want to have an educated opinion.

Thanks

The miss sounds like your EBV. Which is normal until it warms up.

EBV is disconnected.
