P0266 Any info

[jackal]

The truck sat for a couple of days and I started it up to move it today. When I cranked it kinda sounded like the batteries were dying about the time the engine hit Top Dead Center. I let the glow plug light go off and cranked it the engine cycled twice and on the third time around it started. I went to town to get fuel and on the way I checked for trouble codes, P0266 was the only one. I cleared it and no codes now. Cyl # 2 Contribution/ Balance fault. So I guess I have an injector going bad now? It is a 2005 6.0 with only 40,000. Is there anything to be concerned about? I do need to take it in for a vibration at about 35 mph, and only if you are trying to keep that speed by barely pushing the throttle down. I figure I'll mention the code when I take it in. Any input would be appreciated. sorry for the long post. And I did just change the fuel filters about 4 weeks ago.

How does it run? Sometimes when the batteries go low there will be random codes set. Does it clear and stay off? If theres a misfire or something you need to run a buzz test, and most likely replace the injector. If its running fine clear the code and run it, it may just be from the low battery voltage. Usually when low battery voltage sets codes there is alot of codes tho...

Thanks for the info. It Runs great except a low speeds like explained above. I will try running the buzz test. Sorry for not replying sooner I've got the flu so when I get to feeling better I'll try it.

Might of been the cold start with low bat, glows didn't put out enough so the first few cycles were misses. Was the start rough?

Clear it and look for it again.

The start was a little rough. but it cleared right up. And the code has not returned yet.
