My 93 has the older ECU. It has personality and occasionally needs that 15 minute nap / attitude adjustment
Check your air tube- hard or soft? I cracked hard tube changing my first air filter. Weeks later it caused a similar stumble at the first complete stop after warm up.
Suction cup for glass/dents squeezed into the lower corner worked as a “short-term / keep the rain out” $5 fix.
It lasted much longer than I expected with no tape residue. Not good for off road bumps or curious back seat passengers.
