Boy am I dissapointed. I just turned 2800 miles and got my first CEL. Cycled the key and got P0301 and P0513. The P0513 is an invalid SKIM key, which doesn't bother me, I am sure happened at the dealer the other day.

The P0301 is a misfire on cylinder #1. It was starting and idleing a bit rough today, otherwise seemed to run fine as I put about 150 miles on it. I did notice a little blue smoke when I started it at work. Anyone else run into this on a new truck, and what do I have to look forward to? It will be going to the dealer in the morning.

 

Have you checked your oil level?

 

Yeah, it didn't appear to have lost or gained any. It was right at the full mark.

 

Well I picked up the truck. They reflashed according to 18-003-06 and 18-005-06. It seems to be running smooth, although my idle is now 800 instead of 750. I am a bit skeptical of this fix, especially since according to the tsb index these tsb's do not apply to my truck, built 03/06.

There was also a couple other numbers, 18190615 and 18190421 that showed up on the repair sheet. Any techs know what those would be?

 

That seems a little strange. The first tsb you listed is just for diagnositic proceedures for flow testing the fuel system. The second doesn't seem to apply at all. None of the codes or symptoms you listed show up on that tsb and it's out of the production date range. To me, it looks like they just updated the ecm to the newest version and wrote the related tsb on the ro so they can get paid.
The second set of numbers I don't recongnize.

 

The first tsb is for the long crank reflash, which I have had trouble with from time to time. I agree, the second doesn't seem to apply.

I don't know, I am concerned because I have a 2000 mile trip next week. Driving it today I am not convinced the problem is fixed, it still seems to idle a bit rough after starting. But so far no CEL. I will check to see if it threw any more codes tonight.

Dangit I hate this. A brand new truck and I am worried about taking a trip with it.

 

Ah, I glanced at tsb 14 instead of 18, but that doesn't list any of your symptoms either. Maybe they didn't know what to do so they just flashed and hoped it would go away. I don't see how they got away with doing two flashes anyway because the second flash will erase the first, they should only have done the flash that has the newest part number.

 

Are those other two numbers the part numbers for the flashes by chance? It is definately idling rougher again, but no CEL or codes as of today. I have a feeling it is only a matter of time though, because it is acting exactly the same as it was before the previous CEL.

 

Ah, those numbers are the labor ops for the flashes. I am used to seeing them with dashes like 18-19-06-15. I would take it back and see what they do. If they don't fix it the second time, think about going somewhere else. If it doesn't get fixed that time, I would be on the phone with Chrysler right away especially since the first repair that was made shouldn't have been done.

 

Well it is progressively getting worse, I am going to have to go back in. After reading a bunch of threads on here, the symptoms act like I could be losing an injector.

I have a feeling the dealer won't do anything unless the truck has a CEL or tow truck attached to it. The next closest dealer is 65 miles away so that really isn't an option.

 

Well I have been following other threads on this subject of rough start and idleing issues, but I figured I would update my own thread instead of hijacking someone elses thread since it is a bit of a long story.

As stated earlier in this thread, my problems started way back at about 2800 miles. Well based on the dealership advise and against my better judgement, I let this go on for a while. Dealer kept telling me at service intervals to run fuel additive (yes-even ATF which I did not do!!), so I have been running PS, and they suggested to wait and see if it got better or worse and throw another CEL. Well finally at 14,200 miles I convinced them it was not getting better, and they diagnosed the #1 injector was sticking open. Injector was replaced, and my cold start issues disappeared. They suggested I needed to replace my fuel filter, however I had just changed it the weekend before, and the previous one was installed at 7500 miles. I have never found any water or sediment in the fuel bowl.

However it still ran rough at hot idle, and I would occasionally get some light surging at highway speed. So at 17,300 miles they pulled all six injectors, verified they tested OK and put new washers under them. Also reflashed computer and sent me on my way.

The hot idle problem still persisted, so yesterday at 19,200 miles I took it back in. They had the truck until late this afternoon. The tech stated he replaced 4 valves (2 intake, 2 exhaust) due to excessive carbon build up. He said my idle time was 30% which was excessive. I find this hard to believe since most of my driving is interstate highway on a 150 mile work route that takes me over two mountain passes. I never let it idle more than a minute unless I am at a long stoplight. And I have put 19,000 miles on in 9 months which isnt exactly puttering around compared to a lot of peoples driving habits.

Now the rest of the story. I read the paperwork after the service writer finished it. Turns out that the tech diagnosed low performance and compression on #1 cylinder and replaced all 4 valves, which ironically is the cylinder that had trouble way back at 2800 miles and had the injector replaced at 14,200.

I can't help but think that if this was correctly diagnosed from the start, that we could have avoided all this hassle. Hopefully it hasn't caused any long term damage to that cylinder. I depend on this truck for work, and it has been frustrating with four trips to the dealer already. The upshot is that the truck finally seems to be running great. It's amazing how much quicker the turbo spools and how much better the throttle response is. Hopefully it is fixed for good now. I will have to see if my MPG improves after all this.

One more thing, thanks to eveyone at DTR for providing a forum to document this stuff. Maybe it will help someone else out, and it is possible I may have to refer back to this thread at some time if I have any more trouble and end up in a battle with DC.
