well this might be a maintenance but this didn't happened untill i stared modding my car but i cant remember when this started and never took the time to talk about it but...

when i start my car its fine i drive 50 100 feet the car boggs and i usually just ride throught it , but if i start my car a few minutes later it'll bogg out and die.

so uh can any one help?

i had the same problem and cleaned out my egr valve and did some maintenance and replaced my pcv valve and fuel filter all in one and them i didnt have the problem anymore and i replaced the crank shaft positioning sensor but that was becuase i have a half shaft go out and i have no splash sheilds and the shaft came off and hit it but it was only 10$ but 1 of those things i did all at once fixed my problem hopfully someone else will no which one it is that did it so you dont waste money but i did the maintance things i thought needed to be done at the time hope i could help!!

give it a tune up then go from there . throw in a b12 fuel injector cleaner.
