First off ill tell you about the truck its a 06 Mega cab six speed, exhaust is only mod truck has 105k drove it today four hundred miles to gatlinburg TN did great all the way nothing out of the ordinary drove it to dinner starts missing on the way back noticeable I could feel it idling and when idling in gear as well as when first accelerating, just changed the fuel filter, no codes, what do y'all think

 

How cold is it? Fuel jelling? Do you have gauges/what is the fuel pressure?

Check your oil level, see if it smells like diesel.

 

Its only thirty, was gonna check oil in morning scared to pull that stick just changed the injectors in the truck I just traded in on this one

 

Still missing its kinda odd sometimes it clears up don't know what to do though its not throwing any codes and don't know of any diesel shops around here, got to head home on Tuesday morning four hundred miles and scared I've for a bad injector oil level hasn't risen yet bit I'm scared it won't make it, it runs better highway driving but around town light to light it gets rough

 

Still no codes showing up

 

You didn't just happen to refuel before all this started, did you?

 

Got a little over a quarter left since the last fill up, I was hoping that could be my problem its got grey smoke now when it starts missing at idle not bellowing out but definitely there think ill change the filter again if I can find a parts store

 

Really think it's an injector, anyone ever dealt with cummins having any mercy on a truck that just broke 100 k. Warranty wise

 

could be a electrical issue with the injectors mine starts the same thing before it completely goes nuts

 

Any one know a way to isolate injectors to test if I'm gonna have to go through this again I'd like to have them all flowed and tips maybe 50 horse

 

About a year I noticed my truck as idling funny. It had a different than "normal" vibration to it. I don't know how to explain it but the truck shook at idle and just didn't feel right; it drove fine on the highway and didn't throw any codes or anything. I took it in and turned out to be a bad injector. It was under warranty at the time with under 36,000. Good Luck!!!

 

Certainly sounds like an injector.

Grey smoke is fuel and at idle that is most likely a bad spray pattern sticky delivery valve in the tip or air in the system.

Since the fuel filter is under pressure there should be no air. Try a gallon (or what ever the correct mix is) of Power Service adative.

There is a Tractor Supply store in Sevierville on 441. They will have it. Also there is a Walmart between Pigeon forge and Sevierville.

One other thing. Don't idle it as it could wash a cylinder and cause ring problems. Probably will be fine on the open road with some rpm and load you might not even notice it on the hwy.

 

I appreciate your response ill be going to Walmart here in a bit, like You said it does.fine on the highway but its sitting at lights is when it starts so you reckon it'll be alright to drive home then

 

Did you check that wire that runs under the oil filter? Lots of threads on this subject. Apparently it can rub itself raw against a bolt and then you get intermittent arching resulting in a miss and smorke. I havent't had this problem but what you describe sounds similar to what happens. Believe this wire runs with part of the AC circut.

 

Haven't thought of that will check
