I had an interesting drive to work yesterday morning. After working a 18 hour day and 2hrs sleep, I was back at it. When I left the hotel, it was 15deg on the console and I didn't have much time to let the truck warm (gave it about 2 minutes, but I was already late). I idled it out to the stop light and when it turned green, I have it a little juice and started on one of those ride-of-your-life kind of deals. I ended up hanging on the brakes and trying not to maul over the line of cars ahead of me before it finally let go and released. I carefully limped it to the plant and had a nice conversation with Dodge customer service -- finally had to demand that they send a rollback and pick it up (the nice young lady kept suggesting that I drive it to the nearest dealer).

Of course, after the hot soak it wouldn't do it again for the dealer service.

Anybody else have the same problem and is there a TSB or anything from this? Dodge customer service didn't seem to care much once they found out that the problem didn't cause an accident. I sure don't want to go through that again as I could very easily have hurt someone.

Mine is a '04 QC 4x4 with the 4.7

If they refuse to do anything, I'd be sure to clean the TB and try to get some grease on all the moving parts of the throttle linkages and cable.

I've heard of water getting in the linkages and freezing, but that would go away after it warmed up. I've also heard of carbon making the throttle stick, but never i the open position. Could have just been one of those freak things.

I'd start by doing what I mentioned above.

As a side question, does Dodge run coolant through the TB?

 

I believe that they cleaned the butterfly and surrounding area as well as the outside linkage and probably sprayed some lube down the cable jacket. If I had to guess, it may have got water pushed into the throttle cable while the dealer was prepping it (just bought it used a month ago).

The problem went away after the engine warmed and sat for a while, so it had to be something out on or in the TB.

I haven't noticed any plumbing for a water feed to the TB, but have owned other vehicles that did.

Sounds like they did about all that they could do without being able to replicate the problem. Wow, there still are good dealerships/mechanics around. I can think of a few that would state "could not replicate customer's concern" and send you out the door.
