low end stumble

[niagara nsx]

hi
I have a 1992 NSX with a drivability problem..142,000 km
when shifting up there is a stumble in my acceleration at approx 2300 rpm
it runs great higher RPM and even this problem is very slight it does not trip the check engine light ever
I changed my plugs only 24,000 km ago
someone suggestion a fuel additive that counters the ethanol we have here
I use sunoco 94 octane..and have never put any additives in the car..and am reluctant to start

any suggestions?

Warwick, NY is in the Hudson Valley, Orange County, NY. I am just above NJ in NY State.

However I will be in Niagara Falls Thursday on route to NSXPO2009.
