Just that one annoying glitch.
The 3.0 has a cam syncronizer. These are known to cause poor engine idle, but get blamed for anything relating to engine performance. It's tucked back behind the rear (left of center towards the passenger side) and the filewall. If it's suspect, wait until the engine cools down, then crawl up on top of the engine, and with a flashlight, look for it, and remove it's two top screws holding the sensor to the housing. Lift off the sensor, and inspect the "cam" that is used as the trigger to the sensor you have removed. If it's pitted, worn (from "slop" or wear of the shaft within the housing), it needs replacing. Search this site or google "Ford 3.0 V6 cam sensor", and read about it. It's recommended they get changed every 80K, but don't assume it's bad. If it is bad, it causes a poor running engine, and left un-replaced, can cause further damage. Again, google about it to learn more.
