engine hesitation at 2000 rpm! Cummins 600->
MedicShawn
I don't know whose truck is the few and far between, yours or mine. I recieved my truck on 02/02/04 and I now have 2,800 miles on it. In my opinion it is as bad maybe worse than the day I drove it off the lot. My dealer is suposed to be one of the highest volume dealers in the South and I feel like I have got nothing but generic answers for all of my concerns. Not to mention them not calling me with answers when they said they would and different answers from everyone I talk to. I love my truck and will always drive a Ram I just want to resolve the problems. I don't understand why there would be problems with a change over, with the resources DC has and proper planning they should have been able to release this new engine problem free. If the problems with my truck are exclusive to my truck then why not admit it. One of the answers I recieved was that the rocker arm was hitting the valve cover. If this is true then all trucks should be doing it. They won't even allow the dealer to remove the valve cover to varify if this truely is the problem.
I wonder if they would flash my computer back to the old 305/555 settings thus removing the infamous third injection event.
To those wondering wether to place an order or not. This can be an excellent truck and in many ways it already is. I would deffinatly wait at least until after the March flash to see if this is going to resolve the engine problems. As for the rear end, this problem has been around for a while and it doesn't apear DC is willing to do ANYTHING to resolve it.
For now I'll just turn my radio up, grit my teeth, and try to be nice.

papaperk-
See my thread over on TDR: http://www.turbodieselregister.com/f...threadid=93100
The temperature just went up to mid 50's from low 30's. The hesitation has nearly vanished. Where are you located? You have cold weather? I wonder if the guys not seeing the problem are in warmer climates?
Another thing, I have come to the conclusion in order to reproduce the hesitation, the truck must be at full opt temp and it be cold outside. If you test drove another truck cold it won't do it until 20 ~ 30 miles and hot engine- at least I have found.
Oh and my truck was built on 1/04/04
afacey

that is true

I am in the eastern midwest.
I have driven the truck in 40 degree temps through 20 degree temps. Truck does the hesistation everytime. However like you said it must be up to operating temps. Around 200 F. So that deffiently indicates a engine management problem. I wouldn't doubt the truck may run normal when the temps outside are warmer.
You may be right about test driving another truck. However I ran one and got it up to nearly 200. And it had no problems.
Maybe we should have a survey posted to poll where people live and if they have a problem.
I hope DC fixes this problem!!!! I am getting a new truck by the way. I am not going to mess with the problem. Hopefully the new one won't have the problem.

And, no flame intended, but, if your truck is otherwise OK, why not wait to see if the new flash cures it.
Dealer was kind enough to order another truck for me. He new I was disappointed. They will reprogram (due in March) my old truck and sell it probably for more than I paid so everyone hopefully will be happy. I am gambling that the new truck will not have the problem because it will be built after the apparent hold. I am also gambling on the $2000.00 rebate which I got on my current truck. I may not get it on the new one but I feel the risk is worth it. I want the truck right.....right out of the box.
At least someone is getting some satisfaction.
Are they going to let you drive your current truck until the new one comes in?
Congradulations, I hope the new one is better than your current one.

Rocker hitting Valve Cover
Stack_climber I have had my valve cover off before, and I can tell you that there is NO WAY a rocker arm can be striking the valve cover. Not even a chance!
It's easy to remove the valve cover if you want to look things over. Take off the plastic cover, disconnect the hoses to the breather, and remove 6 bolts. Valve cover comes off. Gasket is resuable many times over. Might check to make sure nothing looks out of place or for loose rocker arm studs or badly misadjusted valves (I checked mine and they were dead-on).

Well, Papa - the looonng wait begins for you. With the current hold, it may be awhile. May be worth it for you for the peace of mind. Sounds like your dealer is standing behind you, and that is what we want to see.
I don't mind to wait. Patience is a virtue. What I do mind is having a brand new truck that is running poorly.
So far I am very impressed with the dealer. I have always be polite to them and I think that really pays off. The dealer doesn't build the trucks they just sell them. I think sometimes people forget that fact.
I just hope my new truck will be a good one.

PapaPerk, glad to hear your dealer is standing behind you. Unfortunate circumstances though. When your current (old '04.5) truck gets reflashed, are you going to drive it and maybe keep it if it's right or have you already turned it over to them? Did you order the exact same thing?
Truck is already gone. Dealer took it back. Now I am just waiting for my new one.
The new truck is identical to the old one. But hopefully without the hesitation problem!
I hope DC and Cummins get this stuff straightened out.
I don't care what anyone says. A customer should not have to put up with problems on a new vehicle. It is ridiculous! And I know that many people have had trouble with Powerstrokes and the DuraMaxx as well. The Big 3 needs to put quality and customer satisfaction at the top of there "to do list". If not, foreign auto companies are going to crush them. This has already happened to the car market. I hope it does not happen to the truck market as well.
If people have problems with brand X and brand Z has no problems....guess who will eventually sell the most vehicles. Brand Z. No one wants the hassle of unreliablility. I know I don't. Life is too fast paced and precious to spend it in an auto shop fixing stuff that should never have been broken to begin with.

I'm ready for someone else on the infamous "waiting list" to take delivery and my fingers are crossed that this problem is not widespread. While the problem doesn't appear to be rampant, it is early on. Cummins seems to be on top of the situation. Correct me if I'm wrong, but it was quite a while before a reflash became available for the dealers on the 6.0 Powerstroke.
The hesitation will be fixed by the re-flash. It has to do with the ECM being temporarily "confused" by the missing tooth in the tone wheel. When it happens, the pilot injection is partially lost and sometimes if you get it just right the pilot injection is not given at all and that cylinder misfires. Its a very small "area" of the torque curve, so it shouldn't happen at WOT or light throttle.
