I have a 2003 Kia Optima V6 with 100,000+ miles on it. Ever since i’ve had it (used) when i fill up the tank it won’t start unless i put my petal all the way to the metal & keep the RPMs up around 2000-3000 so it won’t die. Doesnt matter how much gas i put in either. It could be $5 worth or $45 worth. Ive tried lettin it run, taking gas cap off, changed the spark plugs, replacing the gas cap, Putting heat in it to get water out. It runs fine after i get it going though. Im stumped and so are the mechanics ☹ Any help would be much appreciated. You can email me at [MizJoy@yahoo.com](mailto:MizJoy@yahoo.com) THANKS!
