My 1992 100S V6 Automatic had the same problem a couple of times.  Each was
a different remedy.  o2 sensors, vacuums leaks, low octane fuel, fuel
filter, dirt MAF sensor, bad seal at plennum to intake manifold (AKA: donut
seal) bad breather lines at back of heads that attach to plennum and just
recently was the Gas Tank Cap!  I notice a gas smell and a hissing at the
filler spout after driving the car on a hot day.  Replaced the old cap and
presto, new car!
Happy hunting!  But worth it, each one found will noticeable improve
performance and gas mileage!
