I have a 2003 GT automatic, have had starting problems since January. It only happens when it is warm, never after sitting for 4 to 8 hours. Had the fuel filter and IAC replaced (by dealer), problem continues though, It feels like it is starving for fuel when it happens, generally takes between 2 to 6 times to start (but not everytime, maybe 1 out of 2 or 3 times). Mechanic at the dealer thinks the fuel may be vaporizing, but not sure. Its a high volume dealer and he is the master mechanic, said he was stumped - Any ideas?
