My sloooooooooooooooooow 04......
GRRRRRR!!!!
This vehicle is really starting to bother me.
Every once in a while, I shift into 2nd gear and hit the gas.......Nothing....Sputter.....pop......
Then, all of the sudden, AWAY WE GO!
"Nothing is wrong" says the fearless Dodge dealer......."there are no codes"........."you have the most recent PCM flash"..............
WTF I SAY??????
I'm thinkin fuel delivery problem, but how do I prove it?

Mine did that to me just recently. I was in first I stepped on it to go and it went "brrrrrrrrrrawwwwwwwwwww" and it almost died. Then all of sudden, "SNAP" it went. I swear I about rearended the person in front of me it lunged ahead so hard. And it was fine after that. I don't know if it has to do with the weather or something, because it rarely ever happens to me. If you ever figure out what the problem is let me know. I'd like to know what it is.

If it's a manual, it could be the way you are shifting. In fact, that's probably what it is if you have a manual. You can't just relax in low RPM in 2nd gear and then go or it will bog out sometimes.

Continue to monitor the situation. As the wether change in my neck of the woods has been fairly abrubt (Snow just before Easter to 77 already 2 days ago) the gas you may be recieving may been a winter formulation or vice versa and depending on what you current weather is may bee incorrect. This is known to cause driveabilty problems. Generally just poor performance but who knows. If as we get farther into spring it still persists or gets worse then I would look into getting it serviced again.
Codes are not everything, yes they are most of the time a very reliable and valuble too but they can be misleading or not evident at all. As some things require repeated (consistantly) problems before setting a code. This is why a dealy or real engine performance shop uses a full scanner that lets a technician view live data and some will even have what is known as a flight recorer. So they can catch glitches. You press a button and the recorder will record the pervioius 30 sec + the next 30 (or what ever is setup) and view data about what happened. They can also test sensors for acuracy. Imagine if you have fuel pressure problems and you sensor is broken always feeding back near normal pressure. Hmmm no codes but no fuel either. Yeah misfire can be a problem eventually but if you just need a fuel trim adjumnet and you don't get it. Just food for thought.
So in the interim just look for simple things suc as try changeing gas stations if you always use the same station. Fuel injector cleaner. And always check your air filter. If dirty or possibly salt packed replace.
For those of the modified persuasion (ie. CAI) check you throttle body for dirty MAP sensors.
For those with o-scopes check you thottle position sensors for smooth voltage(or resistance) curves. Any spike or holes well you may find a problem. Imagine you have a open were you hit the throttle in one particular spot and all the sudden even though ou are giving ~3/4 throttle your pcm sees Closed Throttle. Oops. Not as the you flex you foot all the sudden you move to say 74% or 76% and not 75% and you are off to the races again.
Just stuf to thing about and try. If you are getting this at light and heavey throttle that situation may not be too plausible but you see the intracacy of the problem. Just keep this in mind and start logging what you were doing. Turning left, 1/4 throttle, rain, full tank, engine cold, only shifting into 2nd gear, ets., etc., etc. This will help identify possible problem areas. If you data is very consistant they know where tool look. If it did something funky once or twice and you can't be very specific then it ma be impossoble to replicate. Imagine if the problem only happens cold but they have a couple of very similar issues in known issue archive about the car being warm they may be barking up the wrong tree. Make sure to give as much help as possible.
