Hey guys I’ve searched some other threads before I post but feel like there there’s nothing directly related to my issue, my truck has been at the shop for a little over a year now and I want it back, I’m going to go get it in the next day or to so I’m looking for some insight

first- one minute it would run like a champ and the next it was weak and struggled to manage 55mph then it might go right back to running like new this happened couple days then I got CEL code 11, I cleared it and drove some more same thing again but now we are running rough and spuddering now we got CEL code 11, 51 and 41
running fine at idle but hucklebuck and spudder no power to pull out of the driveway when I give it throttle
So I haul it to the shop sits a couple days and mechanic calls it’s running fine he’s done nothing to it so I drive it around the block and it dies, tow it back and now there is no injector pulse with noid light and he said he tried another ecu and no change still would not start

i know this was long but I wanted the previous events known thanks for your help

 

Quite often, the connectors to the injectors get old, and loose in the plugs. A little bump, bad. A little bump, fine. Something to check, maybe....

thank you every little bit helps I’ll definitely take a look at them
