so heres my hypothesis (or somethin) kinda long but input is needed =)
ok so heres the deal..this been goin on for quiet some time but never really turned into an issue...but its bogglin my mind.
lets say i drive my car for a fair amount of time(lets say a 35 mins of driving) and ALL of my driving is highway driving(dallas freeways)...after the drive ill park my car and if i come back, say roughly within 2 hours of the last drive, and try to start up my car,...
and itll be really rough starting and sometimes take a couple cranks for it to fire up, and it itll idle a tad rough until i start driving...and AS SOON as i strart moving decent speeds the car runs great...and the more i drive it the better itll run..id say within 3-4 minutes of driving its running perfectly fine..and really this car runs really great..another thing is my car runs VERY cool,due to a new radiator, and my "custom cold air intake" this car never heats up past the first THICK white mark on the gauge..car really runs great after this short tamper tantrum...what is the deal???
ok one more thing..this keeps crossing my mind...my older bro back home always had big old broncos that he "roided" out(460)..one minor problem he had was VERY similiar to mine..what he said,.."vapor lock"---after the truck would sit all the heat from the engine would rise up and heat up the metal fuel lines totalling vaporizing the fuel..starving the engine of fuel upon restarting...once he drove it for a couple minutes it would run perfectly fine!
is this possible for my case?? ^^^
and note: im replacing my plug wires,dist cap,dist rotor all on wednesday.
what the dilly yo?!?!?!

I am not familiar with Dallas.....
Is it really hot right now? I am in area of CO where air temp can be cool, but the heat coming off of the pavement can be intense. The sun is pretty strong here. The most it has done for me is on very hot days my fuel pump will whine a bit. So temperature has messed with my fuel system, but not to the extreme of vapor lock.
Currently my 12V is running rough for the first few minutes, but I believe this is due to a O2 sensor that needs to be replaced

isv controller...
It helps control with amount of fuel your car is getting from the air going through the isv. Usually if it is bad you'll have the starting hesitation for the first few minutes with a rough idle but then also you will run a little hot when in traffic. Fixing this problem won't be easy, it could be almost anything fuel related, start with easy (cheap) stuff and go from there. Like everyone said it could be injectors, it could be a fuel pump, it could be the ISV.
