Ford Windstar engine pulates

I have a 99 Windstar with about 98000 miles on it. When we are driving down the road at about 50 mph or going up hills, the engine will "pulsate" and the tach bounces up and down.. It's not very predictable.. I took it to a mechanic once for this but of course, it didnt do it when he took it out. If anyone has any ideas, I would appreciate it! I replaced the MAF and fuel filter.. Not sure what else to do to help fix this problem.

Thanks!

first you need to have a compression test done to make sure nothing mechanicaly is wrong, then the pulsating could be either electrical or fuel related, you might install a fuel pressure guage into the system and tape it on the windshield and drive around until it pulsates, check the guage and see if it pulsates with the engine, if so then the problem is most likely a fuel pump problem,

how long since the spark plugs have been changed?
has the fuel filter been changed?
have you checked for any trouble codes?

these are just a few of the things to check.
