HESITATION WITH HARD ACCELARATION

1993 Subaru Legacy

Engine Performance problem
1993 Subaru Legacy 4 cyl All Wheel Drive Manual 180000 miles

This car recently developed a misfire like symptum while applying a hard accelaration in lower rpms.
It has a new set of plugs and fuel filter. What do I do to fix it? Thank you for your help.
