Hey I had the same problem and replaced almost everything you did, and believe it or not it was my idle air control valve on the throttle body. Mine is a 5.0 GT but yours might be the same problem. Good Luck!

i have the same problem right now... do you have a code reader?
if its throwing up code 334, then its the evp sensor getting to much voltage... take it off the egr vale and grind down the tip of the metal rod inside it untul it read .40-.63 when the egr is opn and the motor is running and at operating temp....
check my thread, and there are som other tips in there and a link to a site that gives you more specific directions!

Good Luck
