2003 Ford Taurus SE 3.0 engine code U s.o.h.c. It is like it coasts for a long time like you are on the gas but are not! It is weird because it is intermitten and does not do it all the time!Mileage is down a little! When you are driving down the road and it is doing this weird run away thing if you switch from drive to neutral the R.P.M.s rev up beyond the R.P.M.it is at then come down to what seems to be normal!What is going on here? Any ideas? The car has had a new computer do to P.C.M. being erratic and new T.P.S.and M.A.F. The car also had the run away symptom before new computer T.P.S.and M.A.F.Thank you for your time!!!

try cleaning the throttle plate on both sides as well as iac hole. they stick due to oil and can cuase this as well as engine stopping when coming to stop. if that doesn't cure it have checked for a vacuum leak like ahose off ,split etc.
