Heat Soak misfire upon startup?

Just finished a 14 hour drive from Virginia to Florida. As a whole the truck performed great, but I did notice something that I had not before. After pumping gas, or running into a store, when I would start the truck it would misfire a bit. Revving it up solved the problem immediately and it ran smooth from then out. In running around town, it did not do it, until I drove for another couple hours to really heat everything up.

 

It behaves very similar to a 4.0 XJ that has the fuel vapor issue, except less severe. I don't think it is running hot although I do only have the stupid on/off temperature Guage from the factory, so I have no idea what Temps it is actually running....

 

No CEL except for the passenger side 02 heater circuit that came on approximately one week after I fixed the drivers side. I swear this truck is a tank but I need to pull out the damn CEL bulb, fix once thing and then something else triggers it....

 

Thanks in Advance!

Now FLpath.
