The 2003vue runns fine idles fine but dies when traveling down the road no missing or hesitation

most likely it is not actually a misfire it is the overdrive/TCC solenoid kicking on and off, it is a common GM transmission issue

SOURCE: Idle fluctuates

Its could be a few things. Most likely cause is you IAC (Idle air control valve) If this valve gets clogged up with carbon it will cause a idle surge on cold starts like you are describing.

Next your FITV (fast idle thermal valve). When the hot wax inside of this valve starts to wear it will cause a idle surge on cold starts.

did they change the fuel filter??? if so then i would check to see if you have a miss in one of your cylinders this can be chacked as easy as turning your car on and going around the the muffler and listening to see if it makes a funny noise something like a low cough nothing loud just a little cough. if you cant hear anything like that take it in to a mechanic and have then check the pressure in each one of your cylinders
if it is not either one of those that i am not sure either hope it helps

could be a vacuum leak, also get rid of the quadrajunk carb it will prolly help

Please be fast about checking your fuel pump. It is not giving enough fuel pressure.

Cheers.
