did you replace the tps and set it? surging idle is a problem as old as the 5.0. if you go through a search for surging idle you probably will find quite a few threads. also before i had any mods, i had a surging idle and chased all the gremlins. i got rid of mine with a 1/8th in drill bit through the throttle blade. good luck.
