Default Running rough

My 97 PA seems to be running ruff like when i get on the gas..
I did a tune up about a month or 2 ago.. And this week i noticed its running rough when i take off from lights & pickn up speed to get on the highway like the the car vibrates & everything..
Nothings wrong with the exhaust, nothings wrong with plugs/wires ect...
I need help..

Not sure of your description....is this like a misfire? Fuel starvation?

Any codes?

Try running with MAF disconnected?

Check the vac line to fuel pressure regulator, for fuel?

I would say possible fuel starvation.. its like if i take off lightly on the gas its fine takes off smooth.. Say i press the peddle maybe a quarter of the way down.. It sounds ruff & not smooth like before

Screen? What screen....you said you replaced the FPR, that includes everything.

When we asked you to check the vac line to the regulator, we were talking about fuel, not moisture....

the FPR has a screen on the bottom side.. The old one was old & needed to be changed...
And im talking about that! On the old one it was rusted out.. If tht makes sense.. It had holes in it..
