Bad FCA or injector?
 

alright gentlemen got a bone stock 05. The truck started dying or acting like dying at redlights and just really whenever I lay the brakes on. At idle it has a slight lope with a very very light haze of smoke. Sometimes when I hit the gas it will hesitate. The whole problem come and goes. Truck has 157k. It really feels like an electrical problem of some sort but i dont know. Help

if i was guessing it would be injectors. :hellox:

Could be FCA...could also be a solenoid on an injector...

I would check torque on fuel tube nuts and go from there

I would expect it to be all the time, and not random; if it were the fuel connector tubes...

mine would not all the time temperature seemed to be the deciding factor
