I have a 1996 Ford Windstar 3.8. The transmission was rebuilt 7 months
ago and the vehicle has developed a sputtering surge/jerking at around
1500rpm in overdrive and 55-60 mph on the highway. No fault codes are
shown after replacing plugs(double platinum), plug wire set, and the
#4 fuel injector. Fuel filter is clean and I have attemped to locate
any kind of vacuum leak when the manifold was removed for fuel
injector replacement. I am giving up and asking for suggestions,
please help if you have had a similar problem or know a solution to
tracking it down.

it may just be your trans. is a little slow at getting out of over
drive. i have the same problem in my ’93 olds achieva(trans. was
rebuilt about 4-5 years ago). i have done all the same things you have
done(for the most part) but i didnt change any injectors or check for
vacume leaks. it has been almost 5 months and it is still running
fine. so it may just be a little slow at leaving overdrive.
