'These included the distributor and the AFM.
Should those items need replacement after eight years (but only about
30,000 miles)?"

new or used ?  If new they should be OK.
if rebuilt..........perhaps less so.

AFM fits with 'flat spot'.

how bad a flat spot ?
a weak spot in the acceleration curve,
or just falls on its face ?
