Question Missing / Jerking 5th gear

I have a 91 LX 5.0, while driving, and at ANY cruising speed. If I'm cruising at 1900 RPM or below in 5th gear, and then press the gas pedal to pass a car or speed up, the car will miss/jerk. It DOES NOT do it during normal accelerations from 1st to 5th. only while cruising in 5th gear and below 1900 RPM

Things replaced so far:
Codes checked
TPS changed
Distributor changed
Plugs Changed
Wires Changed
EGR valve changed
Injectors changed

Any suggestions?

Vacuum checks have been accomplished! No defects

Not sure about the fuel pressure checks.

The KOER test has been run, and those items were fixed and the things I've stated had been changed by my father before I was giving the car. The car has been sitting for almost a year. It's been in the family for a long time, Its just now been handed to me and I wish to get it all fixed.

So Mr. MJR46

how about you know all the facts before you start trying to tear people down. GROW THE F*** UP, and F*** OFF. Get back to work at your little WALMART job and change some oil and tires!!!

So if there are any GROWN UPS on here who might like to provide their info, feel free to do so. I'm posting cause I have my own thoughts on things, but I would like input from those who may have encountered the same issues I am

you still haven't answered my question OP. how did you check for vac leaks. have your ran koeo/koer since you've obtained the car? if so what codes do you have? if you say none...you're wrong. you'll at least get 1 code IF everything is kosher with your car.
