4.6 Engine Racing
Around the spring and fall, or after a return to the midwest from the south, east or a different region of the country the 4.6 in my Econoline will race.
Example:
Stop, then pull up a bit with just a tap of the throttle will set it off and the engine will climb to about 4000 to 5000 rpm, then to stop it, it has to be put in neutral, then it will just return to idle in about 6-7 seconds on it's own.
What could it be that does it? If I'm not mistaken the 4.6 in the Econoline uses a vacuum acctuator for the throttle...
