I´ve seen a couple of posts where users have written in about their car stalling when slowing down to a stop. Found something interesting in the Moss Miata catalog: throttle damping valve. Here´s a quote from the catalog:
"Does your Miata simply stall as you lift your foot off the gas and come to a stop? If the answer is yes, this little unit is probably to blame. Its purpose is to slow down the travel of the throttle plate which keeps the car from stalling. As the unit wears it allows a sudden closure of the throttle plate which temporarily chokes the engine for air and a stalled engine is the result." Moss lists this item for the 90-93 Miata and is part# 971-300 and lists for $74.95. Mine´s a 95 EGT and has the same valve (at least it looks identical) so while my valve operates normally, others with older EGT´s may want to consider this when troubleshooting their stalling problems.
