Bimmerman,

My 04 Titan does exactly the same thing yours does, usually when I'm sitting, idling at "Sonic Restaurant" or something like that,,,,,usually an extended idle type of situation,,,not usually during short stops at stop signs and such.  I'd guess it happens at least once a week or so.  No, I have no idea whats going on yet.  I'm getting pretty close to needing to replace plugs, so I'll definitely try to verify whether this stops my problem.

Good Luck.

Well, I have some news about my shuttering problem.  I took it back again to my dealership and this time I had a mechanic ride with me.  I took it on the freeway and than drove to my house.  I drove the truck on my driveway and the engine was shuttering.  The mechanic was surprised to how much it was shaking.  He asked me to back up to the street again and guess what?  It stopped, no shuttering.  I drove back up and it started again.  He took it back to the shop and he tested the truck and he was stumped.  The truck will only shutter when the nose is up.  He called the tech people and they haven't heard that problem before.  They stated that he replace the fuel pump since they had issues with it before.  They replaced the pump but it didn't fix the problem.  Now they are discussing with the tech people and engineers.  The truck is back in to replace the torque converter.  Hopefully that will solve the problem.  It's weird how it only does it when the nose is up.  It doesn't do it if the nose is down or the truck is angled sideways.  I will keep you informed on the fix.
