Fueling issue?

[dmahlikGT]

Im gonna try and make this short. 04 GTP has an occasional rough idle upon startup but rough idle everytime i fill up gas tank, like to full and start it up right after. Other symptoms; i seem to burn thru gas a bit quicker then usual but im tracking it on the DIC starting today just to make sure, and around 2 of the injectors is wetness on the LIM as if fuel may be leaking.? Im running premium 93 octane like im supposed to, car just turned to 98k, and no other symptoms besides those 3 above. Any ideas? oh no codes either.

Clean the TB yet?

And maybe the evap system is causing some sort of problem when you fill your tank full.

Canister Purge Solenoid Vent Valve, mine was doing the same thing except it got to a point when I would fill the tank up completely, it would have a very rough time starting, had to build up a lot of fuel pressure before it would start. It also caused my car to get terrible gas mileage. The wetness by the fuel injectors worries me a little, take a Q-tip, or use your finger if it fits in that space, and smell the liquid to see if its fuel, or something else. lol... Best advice I can give you on that one.
