answers to questions..

no i had a quarter tank of gas so it was not right after filling up

it only happens on long hauls...not small drives..
and i was really mad at the time so really it was about 5 sec of smoke..it started out little then alot then it dissapears..
the car at the time did not stutter shutter or jerk..rpm was normal no movements..it was like 92 degrees and the water temp was a hair above middle line..

i checked the engine bay and underneath the car and no signs of leaks..

i think it might have something to do with my fuel pressure valve..it does not keep pressure when car is off for a long time..i have to turn the key to position one for like 2 times and then the car starts normal (to avoid hard start)
so i am not sure..
and suggestions now, does this help
