Hesitation/Stutter at 1900 or 2200 RPM
I have a 97 SRS with 140K miles.

It is a momentary hesitation (or stutter, per previous post). It is literally about a half a second, where it's as though the engine is not getting gas fore that split second.

Then, out of what seemed like nowhere, it happened again. Same cycle of events as the first time it all started. Hesitated a number of times during and shortly after initial "event". Then over a couple weeks, it diminished, and now it
